birth control
"I have used the paragard twice now. The first time I had it inserted was a month or so postpartum. The insertion was painful of course and I ended up hyperventilating due to the pain. The device was very effective though and I didn't get pregnant the whole time I was on it. I had regular periods, but of course they were heavier than normal and more painful than normal. As time went on the periods got more and more painful. I started having severe back pain. I'd get these horrid back cramps that got worse and worse every period. Eventually I couldn't take it anymore and had it removed. I just used condoms for a while afterwards. A few years later I decided to give it another shot. My experience was Identical again and I had it removed again."
