i had an ultrasound on december 30th and my gestational age was determined by the doctor to be 9 weeks
and 1 day. i couldnt remember when my last period
was so how accurate is the ultrasound at dating a pregnancy that early with no last menstrual period to go off my due date is august 3rd and hasnt changed. i am with my current boyfriend and i just wanted to make sure its his and not my exs, he is aware that i had sex two weeks after we broke up and we just want to make sure.
