so i already have a one year old. i got the iud about 6 months ago & 3 days ago i had sex, he finished in me. (and it was A LOT) some came out when he pulled out but the rest stayed in there for almost 2 days. i didnt think anything of it. well today ive been in extreme pain on my side and anything and everything makes me sick. ive also felt like bubbles almost in my stomach. i dont have my period until the end of February and i went pee a few minutes ago and am now bleeding a little bit. im just wondering if anyone else has had this happen before. and what it could be.
