I wasn't sure of the exact date of my last period in August so I guessed the 7th at my first appt. My second appt for an ultrasound, I would've been 9 weeks & 1 day making my EDD May 13th, 2013. The sonographer said I was only 8 weeks and 2 days making my EDD be 6 days off. I go back to my Dr Tuesday, was just wondering if this happened to anyone before?
Even by LMP or ultrasound EDD can be off by 2 weeks either direction.
According to the ultrasounds, this pregnancy. I'm 24 weeks 3 days. BUT I was getting positive pregnancy test on May 24th. which would make me around 26-27 weeks pregnant. According to ultrasound I conceived on May 24th. but I tracked everything and know I convinced either May 8th or May 10th.
Long story short, I was getting positive preg test "before" I was pregnant.
mine was about a month off. based on my lmp, they figured i was due march 7th. but when i went for my dating ultrasound, they changed it to april 2nd because i was only 5 going on 6 weeks, and not 8 going on 9 like i originally thought. so... it happens. as long as the heartbeat looks good and baby looks good, then i wouldn't worry.
