I have a 9 month old baby girl. I had an IUD birth control put in 8 months ago. I know it takes a while for your period to restablize, but the last few months, I had a regular period. Two weeks ago I had my period-it only lasted 3 or 4 days. These past few weeks after my period I have had mild cramping occasionally and light pink discharge about every day. The cramping is pretty much everyday, but it only last for about 5-10 minutes at a time, even if its just once a day. I have also had some back pain, mainly in my lower back lately also. I don't really know if these are side effects of the IUD, or if I have some kind of infection. The discharge isn't really smelly or anything. I don't think I can get pregnant with this type of birth control, but I don't know. I hope somebody can help me out here. Thanks! ;-)
