I use Mirena but my last period was five days late and a lot lighter than usual. Since then, I've had fatigue, breast tenderness and swelling, and constipation; I've even been able to express milk. This would be my 3rd pregnancy, yet the pregnancy test said negative. What should I do?
If Mirena contains hormones, they could be messing with your cycle a bit. If the symptoms continue, I suggest speaking with your doctor.
