I'm trying to figure out when I got pregnant. I'll be 21 weeks on Friday, but I don't remember the exact date of my last period?
according to my first ultrasound, they gave me a due date of october 28, 2011. BUT that'd make my last period date jan 21 & I know that's wrong! I don't remember the exact date but I know it was the week before the 21st, I'm thinking the 13th or 16th. IM CONFUSED! please help me figure out when I conceived?
