Okay ladies I had my 3 child 2 months ago and even tho I love kids I think I'm done having them so I need on birth control so there is no accidents. So I used to take a birth control pill that I would only get my period 1 times every 3 months which was amazing my body was very good with it but now I don't want a period at all and the doctor recommended mirena IUD he wants to put it in in a few days so if you have this IUD what's it like how long did it take for your periods to stop.? My body handles birth control pretty well so hopefully there is no issues
