Hello All-
I had my Paragard inserted 2.5 months ago. The first day was miserable but after that I didn't mine. My periods are still trying to get on a schedule but they are really short. My problem I seem to be having here lately is pain during sex. I would rather describe it as pressure than sharp pains but it still is uncomfortable for me. Also, time to time when my fiancé thrusts a little hard I get a sharp pain and ask him to stop but mostly I feel pressure. We have only had sex once full through about a week after I had it placed but since then every time we try it is uncomfortable for me and we end up stopping. Not only has this been emotional for me personally feeling like I am unable to please my future hubby in the bedroom but also I am starting to really get concerned. At my 6 week checkup with my OBGYN she assured me it was in place and I am set to go but I don't know what it going on. I will call tomorrow but have any of you ladies has this issue before? Or have any ideas of what this could be? Any input is appreciated. Thank you in advance!
