My period was Feb 8-11 as normal. I had unprotected sex on the 10th, 11th, & 12th. But on the 17th I woke up and felt so odd all day long. I was bloated and just did NOT feel like myself, I felt the same way all that week. The following Monday, the 19th, I woke up for work and peed and when I wiped there was a light pink blood, and I was like wth is that?! But I had cramps in my lower stomach I felt very nauseous on the 23rd and 25th and my boobs are getting sore. I took a $1 pregnancy test and got a negative result.
I think that the pink spotting could be indicative of implantation, but remember that not everyone (myself included) experiences this symptoms of early pregnancy.
I put your dates into a pregnancy test calculator and technically, you're still too early to get an accurate result on a pregnancy test. I tried it with a normal ovulation schedule along with an earlier than normal ovulation schedule. Taking into account the possibility that you ovulated quite early in this cycle, you still probably won't get an accurate result until Saturday March 3rd.
