I am on the Mirena IUD for two years. I just missed my period this month and am having a lot of pregnancy symptoms. Lower abdomen pain, nausea, heartburn, my boobs are sore and getting huge, and lower back pain. I keep trying to deny that I am pregnant because the Mirena is supposed to be very effective. But I am really starting to wonder if I am. Does anybody have any advice?

I'd go to the doctor. Of course you could be pregnant. Your IUD could have slipped out of place or something.

Curious... were you pregnant or did these turn out to just be side effects?
