yay for ultrasound!! i hate when they say measuring small!! Both of my DDs are on the small side and i keep hearing it at all the drs. i have a heathly 5 year old who barely weighs 40 lbs so i really despise the growth charts, for pregnancy or for kids. you could have a growth spurt in a few days and then baby measures big then small again. so as long as baby is healthy and nothing is abnormal i think it is all ok!
I think their dates can always be a little funny. They told me today that I am 8 weeks, 1 day, but I don't see how that can be if that's technically before my last period. The heartbeat was the big deal for me too. Keep us posted about tomorrow!
