What Is a Chemical Pregnancy and Is It a Miscarriage?

Updated on June 27, 2017

Imagine this: You get a positive pregnancy test only to start your period a few days later. Chemical pregnancies are both common and extremely heartbreaking, yet very little is understood about them.

A chemical pregnancy is a very early miscarriage. The sperm and the egg have met, but while conception has taken place, development beyond chemical changes in the woman's body don’t happen. That's because in very early pregnancy, the cells of the fertilized egg are still developing, but the fetal sac and fetus have not begun to develop yet.

Thus, the pregnancy chemicals, hormones, and cells have started to multiply, but the other physical attributes of a pregnancy have not. That’s why this early form of miscarriage is called a chemical pregnancy. It's a pregnancy that ended when the only detectable evidence of it was through a hormone test and not through an ultrasound, or physical examination by a doctor.

Is a Chemical Pregnancy a Real Miscarriage?

Yes. It was a real pregnancy and it is a real miscarriage.

In fact, it should really be called an early miscarriage since the term “chemical pregnancy” implies that the pregnancy wasn’t real or that it was some kind of mix-up.

What is the Difference Between a Chemical Pregnancy and a Miscarriage?

The only difference between the two is time. Both are the loss of a pregnancy, but they take place at difference stages in the development process of the baby.

Often, and quite unfortunately, very early miscarriages are not thought of as real pregnancies or miscarriages when in fact they are both. And while the physical recovery process is different in a later-term miscarriage than in an early-term one, both bring grief and disappointment.

When Is an Early Miscarriage Considered a Chemical Pregnancy?

The term is used when a woman miscarries after conception but before the fetus has developed.

Typically, it happens at around three or four weeks pregnant. So basically, this occurs at about the time that a woman’s body is producing just enough hCG (the pregnancy hormone) to receive a positive result on a home pregnancy test.

What’s even more confusing about this kind of pregnancy is that they often go unnoticed because they can look and act like a late period. When women are trying to get pregnant they'll chart symptoms, keep track of their ovulation, and take an early pregnancy test about a week before their period is due—these women will know almost immediately if they have an early miscarriage because they're acutely aware of the changes in their body.

However, a woman who is not trying to conceive may chalk her late period up to stress and not even realize that she's having a miscarriage.

Although they're not generally considered much more painful than a normal period, some early miscarriages can be very uncomfortable. Each situation is different.

Are Chemical Pregnancies Painful or Dangerous?

Chemical pregnancies can be painful, just like some periods are painful, but the severity of pain really varies from woman to woman. Most commonly though, they are much like a regular period, but with stronger cramps and a heavier flow.

Since some go undetected, they are not typically considered dangerous. That being said, if you’re aware that you’ve had an early miscarriage, you should absolutely inform your doctor so that the two of you can keep track of any future changes or complications.

Why do Chemical Pregnancies Happen?

No one really understands why chemical pregnancies happen, what causes them, or how to definitively prevent them.

However, contrary to popular belief, they are not the result of a failure to implant. Implantation must take place for hCG to begin developing and for a pregnancy test to come up positive.

In the case of a chemical pregnancy, it’s possible that while implantation occurred, it happened incorrectly or that there was a chromosomal defect in the fertilized egg that caused the woman’s body to reject it.

These early miscarriages happen much more frequently than anyone realizes. In fact, half of all known pregnancies end in miscarriage, and many of these cases are chemical pregnancies.

How to Find Support After a Chemical Pregnancy

Finding support - whether online or off - can help to process the emotions and grief that come with a chemical pregnancy.

Whether the pregnancy was planned or not, going through a miscarriage at any stage can be totally devastating. Here are a few things to keep in mind if you have experienced an early miscarriage:

  • It's necessary to grieve. This may seem like an obvious pointer but in the case of a chemical pregnancy, some women feel an obligation to move past the experience quickly. It's important to accept that what you've experienced isn't some weird phenomenon that's not serious. It is serious. It's the loss of a pregnancy and that has emotional ramifications.
  • You don't have to talk about it with everyone. Chances are this early on, you've only told a handful of people anyway. How and when you decide to approach the subject of your loss is up to you.
  • Don't let the fear of a future miscarriage paralyze you. Again, half (half!!) of all known pregnancies end in miscarriage. That's a sad, hard fact of life that you can't let hold you down in fear. And you're certainly not alone. Reach out and find other women who've had your experience. Online forums are a great way to interact with other women going through the same thing you are.

For those trying to conceive again, there are endless resources available online. Because early miscarriages wreak less havoc on a woman's body than a later miscarriage, not all doctors will discourage a woman from trying to conceive right away as they would with a later miscarriage. Regardless, you should talk to your doctor about what's best for you and your body because everyone is different.

It might also be helpful to find an online support group for women trying to conceive. In the group, you can share stories and tips and feel comfortable with other women who know what you're going through.

What is an Evaporation Line?

Evap lines can lead to a ton of false hope and the brief belief that one is actually pregnant, when actually a negative test is just drying weird.
Evap lines can lead to a ton of false hope and the brief belief that one is actually pregnant, when actually a negative test is just drying weird. | Source

An evaporation line (or evap) occurs as a test is drying. It gives the appearance of a faint second line on the test but is NOT a positive. Instead, it's a shadow of the line that would show up if you were pregnant and should not be mistaken as anything but a negative test. In some cases, women will consider this a positive test and when they get their period feel super confused.

While many test instructions will urge you to read any line, no matter how vague, as a positive result that's misleading, perplexing, and often emotionally devastating for those of us who have ever misinterpreted an evaporation line as a positive test.

So, how can you tell the difference? Most of the time, it's obvious - if you have to squint, hold the test super close and then super far away to decide if there's a line, or if you find yourself holding it up to the light - take it as an evaporation line and test again in two days to see if there are any changes.

        Thank you for this. I have been trying for a baby for a while now and actively track my cycle and have had a series of these chemical pregnancies. However, I am still hopeful that all will be well eventually. I recently had a BFP on Monday last week, 3 days after my period was due. I am now on 5 weeks 6 days and am hopeful that maybe this time its not another chemical pregnancy.

        Thank you so much for this article. I have just suffered a 'chemical pregnancy' I found the term very misleading and unsupportive. I had waited until my period was due to do a pregnancy test and got faint but definite lines on 6 different tests over 5 days including on of the digital ones. By the time I started bleeding I was 15 days later than I had expected my period to start. It was much heavier than a normal period with cramping. Whilst I totally recognise a later miscarriage would likely be more distressing and potentially have medically and physical complications I feel describing my experience as an early miscarriage feels much more in line with how I am feeling. Thank you

        I'm so glad I found this article! I had a chemical pregnancy just before Christmas last year (3 months ago). The ob that told me (not my regular one) said it was nothing and just a false positive test I did at home. I had 4 bright positive tests I did at home before going in. It has bothered me so badly ever since not truly knowing until I read this tonight.

        Great article! Thanks so much.

        I personally resonated with what you said. When you have a positive pregnancy test, there are hopes & a bit of a reality check of what's to come and then after the miscarriage there is a real sadness because of the tiny little being you lost and what could have been.

        I recentley had a chemical misscarriage. I initially went to see my OB because I had pain in my lower abdomen, heaviness and pain every time i had to use the bathroom. OB made me take a pregnancy test and said I was pregnant, she then did an ultrasound and saw a lot of blood in my uterus, she was afraid I was eptopic, but after a 2nd ultrasound said it was a ruptured cyst. I took another blood test 2 days later and my HCG doubled. OB told me to take another blood test in a week and my HCG dropped down from 750 to 34. I'm bleeding like a light period now but no pain. It has been such a horrible experience. I'm glad I found this article. Have you heard of anyone with a ruptured cyst and pregnancy?

        In February 2013, I was almost two weeks late for my period, so I took an hpt. I got a very light positive so I went to the doctor the next day to confirm. The test was negative. I never even saw my doc, the nurse just told me to come back in a week if still no period. Two days later, my period came. It was harder than normal but I got through it.

        I wasn't trying to get pregnant. In fact, I had been having a lot of female health issues and actually had a hysterectomy before the year was out. Since, it didn't cause problems, and I wasn't ttc, I didn't mention it to my doctor.

        However, I have never been able to get it off my mind. Had I been pregnant? Was the positive just a fluke? I knew the only way to find out for sure was to talk to my doc. I saw her this week for my yearly exam. I explained what happened, and she confirmed that I had a chemical pregnancy. She said a positive, even a faint one is still a positive. (I wasn't taking any meds, like fertility drugs, that could cause a false one) she was very compassionate while explaining it all to me, and I felt better knowing.

        Now, crazy enough, I'm sad. I keep wondering what the baby was, and wishing I had known when it first happened. Do you think it's normal to grieve for something that happened almost three years ago? Cause that's how I feel, like I'm grieving. And I feel ridiculous, but can't seem to help it.

        Reading your article made me feel better to understand what happened, and I thank you for writing it. I know it would probably help to talk to someone about this, but who? I don't feel right talking to someone who experienced this recently. I should think they would be on an entirely different level. The only thing I can think to compare myself to, would be someone hearing a loved one passed away a while back, and you're just being told. It's like the grief is fresh for me, even though the symptoms are now gone. Does that even make sense? Sorry if I'm rambling, but it's late and my mind is churning.

        Once, again thank you for writing this. It really has helped me.

        Hi, im 18 i think i had an early miscarriage but im not sure. My period was a week late so I bought a pregnancy test and i was going to take it the next morning but that night i started bleeding really heavy and passing blood clots, it wasnt like my normal period and plus im never late. I was having really bad abdominal pain on and off throughout the night and next day. I was still bleeding so i decided to take the pregnancy test. It was negative. The heavy bleeding and pain continued. My cousin (bestfriend) just had a miscarriage three weeks before so i confided in her about it. She believes i had an early miscarriage but im not sure i did since i never had a positive test. My cousin says it wouldnt have been positive since i didnt take the test until after i was bleeding and hurting so my hcg levels would have already dropped. Does this sound like i may have had an early miscarriage without having s positive test?

        I tried for 5 years and finally got my bfp. Six of them over three days. At 4 weeks and 3 days I lost the pregnancy. While it has been heartbreaking, we're trying to look at the positive side of things. Five years and I finally got a bfp. My body partially did something right. Hoping this next time doesn't take another five years and our little poppy seed decides to stick around.

        So I have been ttc since June and last week got a positive test we were so excited. Then a few days later all my symptoms stopped. my period began very weird period I experienced very bad cramping and back pain. With my regular monthly cycle I don't experience any symptoms at all other than wanting a soda. I got in contact with my doctor and she told me my hcg levels were declining and just to take it easy. I never really thought I could be so emotional over this but I have been feeling a lot of disappointment. My spouse has been so supportive but I know he's feel down also. I am just grateful to have found this page and see someone else say indeed it was a real pregnancy... that's what I have truly been looking for. Thank you so much

        Hi Sharetth, I'm so sorry for your loss. Losing a pregnancy is extremely difficult and I'd encourage you to reach out to your friends and family for emotional support during this time.

        As for your concerns about fibroids, I would ask your doctor what he or she thinks about how they may be affecting your fertility and health.

        Christina, Paula, Susie, and shygirl, I'm so sorry to read about your losses and the difficulty process of mourning that not everyone understands. Chemical pregnancies are so misunderstood and I'm glad that what I've written has brought you all comfort.

        To answer your question, Susie, sometimes it takes the body a bit of time to register that you are no longer pregnant. Once it does, you should start bleeding. If you don't, your doctor may prescribe pills to help your body along or schedule a D&C procedure.

        Christina, I'm sorry that your mom didn't understand what you were going through. I think that sometimes for moms it's like, "I know you, you're strong, you'll get through this," but in situations like this you kind of need a minute to just feel totally devastated.

        Paula, I'm so sorry to hear. Not anticipating being pregnant and then finding out that not only were you but you lost it has to be so confusing, especially at a time in life where you're not really wanting to have children. I know you'll meet your baby someday .

        shygirl, thank you for reading and sharing your experience! I know I mention it a lot in my pieces but BabyCenter has a really great forum for sharing with other women who have had the same experiences, including miscarriage. You might find comfort there as well :)

        Just a reminder to those who have experienced weakness and fatigue during the bleeding that occurs during miscarriage-- talk with your doctor about taking an iron supplement just while the bleeding lasts and for a little while afterward to help build up your red blood cell production. Many women suffer anemia temporarily while going through a miscarriage.

        I had a period on Sept.21 and my cycles are 33-35 days. So on Oct.27 I took a HPT because I had not started my period. It came positive..and so did another one. 3 days later on 10/30 I began having minor low back pain, a heavy feeling, and bleeding. It was like my period was starting, and I bled for 7days. I took a pregnancy test tonight 11/7 and it is negative. I am glad I found your article. It is very comforting to read this and other woman's experiences. It also feels good to.share my experience. Thank you for listening and peace and love to.the other woman who have gone through this emotional experience. .

        What a helpful article! I suffered a chemical pregnancy a year and a half ago. I was 48 and not trying or expecting to become pregnant and went to the doctor because my period was lasting well beyond the usual 6 days. We all thought it was just a pre-menopausal change, but they gave me a pregnancy test just in case. The doctor walked in to show me a very faint positive on the test-- I was miscarrying! Wow. The doctor explained that this was a chemical pregnancy and never developed into anything. I confirmed with her that yes, there had been conception. That was enough for me. I felt immediate shock and sadness. I did not want more children, but a child had been conceived, and was lost. I bled for a few more weeks, passing clotty tissue and was very fatigued. Now I think about the baby that could have been. I am sure I will meet him/her one day. This is definitely not just a "chemical" issue -- it is a true loss and should be approached that way.

        I also really needed to read this. I should be getting my bloodwork back today to confirm that my pregnancy is over at 4 weeks 2 days. I was angry for a bit and then sad. My mom didn't understand at all so I'm so happy someone out there does. It's a loss no matter how early and it doesn't make it "easier" to go through just because it happened early.

        I'm hoping the especially fertile after a chemical pregnancy is a thing for us!

        It has been hard finding information online about what to expect, but this article helped. :)

        Daisy, I'm sorry I just now saw your comment! Although it's a possibility that you had an early miscarriage, I would say it's more likely that you had an abnormal cycle because your hormones were out of whack thanks to the birth control. I'm not exactly an expert, but with a true chemical pregnancy, you probably would have first had a positive pregnancy test, followed by a negative pregnancy test. The fact that you continually had negative pregnancy tests leads me to believe that there were never pregnancy hormones present in your body (thus, you were never pregnant).

        I'm 18 and I think I've had an early miscarriage. In October I came off hormonal contraception and felt like I needed a break from hormones to get back to feeling like me again. Anyway, I had a pregnancy scare and missed my period by three weeks. I took four home pregnancy tests which were all negative. When I did get my period I felt like I was dying. My periods are usually light and I don't get cramps at all, but this time was different. I couldn't stop bleeding, I had agonising abdominal cramps and I passed a lot of blood clots. The bleeding lasted just over a week. My Mum, who suffered a miscarriage before becoming pregnant with me, thought that I might have had an early miscarriage. I didn't think much of it at the time but my boyfriend and I were talking about when we would potentially like to have a child and it has been playing on my mind recently. Does this sound like I may have had an early miscarriage without even knowing I was pregnant?

I think that chemical pregnancies are so sad and difficult and they're not given enough attention. I know from my own pregnancy the ups and downs, the hopes and fears that one experiences even in the moments leading up to taking a test. I hope you can find a good support group (the online ones are actually great!) to comfort you on your journey =)
