I got an IUD and 5 days after getting it my husband and I had unprotected sex. After sex I checked to make sure my IUD was still in place and it was. Well today I went to the bathroom and wiped and there was brown blood I thought it was my period starting so I put a pad on and went about my day well I got home and there was no blood on the pad and no blood when I wipe. I really hope I didnt get pregnant our baby is only 8 weeks old.
