You can't always go off your period cause everyone's body and ovulation cycle is different go off what the Obgyn says cause ultrasounds are more reliable

go by Dr wic said I'm 2 weeks ahead on my due date when my Dr said otherwise since first day of last period.

that makes sense I had forced periods bc my body was irregular:) just listen to you ob

I'll go by wat the Dr says

Thank you guys

Well this might ve tmi but i never had reg ones and didnt have one for 4 months before i got pregnant so idk

I'd go off of your period because babies are all different sizes and that's not a very certain guess.
However I also trust my doctor more than I trust wic nurses.

wic goes by period, doctor goes by ultrasound @march2016mommy757 !
