5 weeks ago the ultrasound said I was at 30 w, when according to LMP I was 32 w. Now LMP is 37, but the ultrasound says 33. And my placenta is now in stage 3 when it had been stage 1, 5 weeks ago! How accurate are ultrasounds for determining age, and can the placenta aging too quickly make the baby lose or stop gaining weight?
Update:Thank you!
Wow I am sorry, it sounds scary even though it may not be. I really think your best source of information is going to be your doctor. I would trust what they say. All I can tell you is that the farther along you are, the harder it is for them to determine a due date. But I would just keep asking questions to your doctor until you feel totally confident in your information.
