Last week ...My doctor said that i was 14 weeks by ultrasound. But she said she's actually gonna count me as 15 weeks. Why is that does she add the extra weeks.??? This week now im supposed to be 16 weeks. But if i would i would do a ultrasound it would say 15. How is my doctor counting ??? My due date by ultrasound is 09/12/13 but my due date that my doctor gave me is 09/8/13
Going by the ultrasound due date you are 15w5d. When they figure your due date original they go by your last period and assume we all ovulate on the 14 day of our cycles. Which is not true. Ovulating later than day 14 would give you a later due date. According to my lmp I am 9w3d but I am only 8w1d because I ovulate later than day 14.
According to lmp I'm 9w1d, according to dr I'm 7w1d but honestly I'm pretty sure I'm around 7w5d-8w, based off when i know we dtd and my kids have always measured small on ultrasound and were born smaller too. But I just let the dr date as she pleases and will prepare for baby on days I know lol
