hi i think it would be best to get to your doctor or gyno just to see what has happened to your iud it would be a good place to start and look for you iud its either slipped out with out you noticing it cant think of hearing of one going inwards but you could be the first. so please seek help. good luck
extreme pain after sex. can't straighten body and i have an iud and can feel the strings. the pain lasted for about twenty minutes or more in my stomach area and it was so extreme it made me cry and i was so scared it caused me to have some gas. i have never experienced this much pain before. i ended up take ibuprofen and it helped but now the next morning i'm still having lingering pain when i move around in my abdominal area.
