I had a Mirena IUD in for a little over 6 months. I had a lot of complications, bloating, weight gain (30 lbs), over heating at night, mood swings, among others. I took the IUD out about 2months ago. Within a few days, I had what I thought was my period for 2-3 days. I have not bled since then and I should have gotten it this last week. I do not think I am pregnant. I am overly bloated, gaining 5-10 lbs in a day. I eat a really healthy balance diet and work out daily with cardio and pilates. I am constipated at times as well. Now I am over heating again. What is going on?!
