Symptoms actually mean next to nothing. A high number of women create them, or look up symptoms and suddenly have all of them. Actually getting pregnant while a Mirena is in is very uncommon. I believe the chances are 1%? If you felt any form of movement from a child, you would show a positive on any test you take. Your doctor will be able to confirm for sure, but I highly doubt you're pregnant.
thank you! haha it gives me more comfort but i wont be totally comfortable until i go to the doctors and they confirm that im not prego.
