I had the IUD inserted right at 4 months ago. In that time my periods have been unpredictable, but no where near as heavy as they used to be which I love. I also like that I dont have to remember the pill every day. Those are about the only pros that I have found so far. Cons include the following, although I cant prove 100% they are due to the IUD, I didnt have these issues before : Severe cramping in my legs, thighs & calves, weight gain of 10lbs so far, unable to lose ANY weight no matter what I do, 2 fainting spells, spotting throughout the month, bloated stomach constantly. Does anyone else experience any of these?
