I just got my IUD yesterday morning and my fiancé wants to have sex tonight. I'm really scared. I haven't had sex in about 8 weeks (I just had a baby and I had to wait 6 weeks and it was too uncomfortable the 2 weeks before I had the baby) I'm feeling fine after the placement, I'm just nervous. Can anyone tell me how bad sex hurts after you get the IUD? I'm also scared because I had a small internal tear.
