I got the Mirena IUD put in February of 2008. I have had complications every since I first got it, such as heavy bleeding and severe cramps. When I got the Mirena, my doctor told me that it was very unlikey for me to get pregnant with it. Recently, I have been experiencing cramps, soreness of the nipples, fatigue, weight gain, moody, head aches, increase in appetitie, strange cravings. I am afraid that I am pregnant. Is there anyone with some helpful advice?
