I had the IUD, and had to have it taken out. First off, I had to go in twice, because the first time, the doctor poked a hole in my uterus, and I had to wait until it healed, before I could get it put back in. Then I was bleeding for about a month, it had started to just spot towards the end of the month. But I only cramped the days that I had it put it in. Then I started to gain alot of weight really quickly, I mean, it was like overnight. they say the IUD doesn't make you gain weight, but I believe it does, because it happened to the rest of my family too. Every time that my husband and I had intercourse, it was very painful, and he started to feel bad that it was hurting me, so there was long time that we didn't have intercourse, because it was just too painful. So I had it taken out, and the doctor that took it out (it was a different doctor that put it in), told me that it was put in wrong, and that I had an infection from the IUD, due to it being put in wrong. I hate the IUD. Some members in my family cannot have chidren anymore, because the same thing happened to them. I don't want to scare you, but I would definately get it checked out immediatly, just because it could be dangerous.
