My crazy story: I had undectected pregnancy at 19 because I was on depo shots. M/C at 4.5 months and found out I had dysplasia. Had leep done. Got married at 21 and tried to conceive for 2 years, nothing. Went for fertility specialist and had hsg in august 2007. All was great, uterus perfect shape and all. Diagnosed unexplained infertility. Got injections for couple months , nothing. Had to move (military) and start over. We went home to my mom's for holiday. Had period December 17 very normal. Found out I'm pregnant January 16 2008. Got u/s that day, had sac but not fetal pole yet. Hcg was high! Got appt with doc in new home state. Did u/s 3/5/08, should have been 11w 2d and was told i'm 13 weeks! I was already feeling lots of fetal movement. U/S pic shows a heart shaped uterus (bi-cournate) with a clear membrane in the middle, but doc didn't say anything. My cousin who has faternal twins swears it looks like two sacs. Could the HSG a few months prior have missed the bi-cournate uterus? ↑
