I had an anatomy scan at 22 weeks and all the doctor said was that everything looked fine and I was due October 14th. But I'm wondering if maybe the measurements were off or the baby maybe 4-5 weeks behind in growth. My last normal period was December 3rd and I had intercourse with one guy from 12/11-12/13th and then I had very light bleeding January 7th. I didn't know if the January 7th bleeding was my period or not. So I'm wondering if maybe I got pregnant from sex December 11-13th and the baby be consistently behind in growth this whole time 4-5 weeks and the doctors or ultrasound not catch it. And my due date actually being September 9th-23rd (according to sex from December 11-13) and me actually being 41-42 weeks pregnant right now instead of being 37 weeks and due October 14th according to the ultrasound and fundal height?? Please help!?!? I'm so confused!!! How long can a fetus stay in the womb? HELP PLEASE!!!!

Any thoughts?

I would go off the dates the doctor gave you. And no, your body won't stay pregnant that long. I think 99% of babies are delivered by week 42. It's unlikely that your anatomy scan measurements were off by 4-5 weeks. xx

very unlikely your out by that much you should also be having regular appointments with you mw who will also measure fundel hight if there is any concern they will send you for a growth scan
if your still worried mention it to her at you next appointment
