I had a negative pregnancy test last month due to a late period. I've had an iud since October last year. Was in a fender bender this morning. Had 2 viable pregnancy and live births to date. Been having "first twitches" in lower abdominal 3x since accident this morning. Once while talking to a counselor right after and the cnsl said it was just my muscles relaxing. 2x more in the last half hour while masturbating. I could feel it against my finger tips,but only if i pushed very hard against my stomach. Felt like i was being flicked on the inside of my uterus. Do you think I'm pregnant even with my mirena?
