I'm so confused right now and have been since Sunday. You see, I had an ultrasound done on the first of the month and was told I was measuring at about 6 weeks 1 day. After looking at the picture myself, it was quite believable. The baby is super tiny. FF to this past Sunday, the 12th of the month, my doctor called me. Weird for a Sunday. Anyway, she tells me that because my periods have always been irregular, they're going to go off of my ultrasound which puts me at 12 weeks 5 days, on Sunday. So technically 13 weeks, today? IDK if anyone has experience looking at ultrasound pictures like a pro, or if anyone else has gone through this... She also said I have a bicornuate uterus, so we have an appointment with a specialist in 2 weeks, but deep in my gut I feel she's wrong... I'm not sure about the bicornuate uterus, but being 13 weeks pregnant... IDK... I'm just so confused... Any insight would be so much appreciated... Thank you....
