Infertility/Fertility - Ultrasounds

Expert: Edward Joseph Ramirez, MD, FACOG - 10/27/2009

Question
Hi Im Eve from MO,

I hear that early ultrasounds are the most accurate, only off by 3 days either way but then I still read that these dates are only approximate and there's no way to know exact dates, so how can you be sure you're as far along as the ultrasounds say you're, especially if you don't know your last LMP? This is all just confusing to me. So if I had an early transvaginal us, can I be pretty safe in assuming that the doc was right about the babys age, give or take 3 days? Thank you

Answer
Hello Eve from the U.S.,

Usually it takes two dating ultrasounds to determine the "approximate" date of delivery ("EDD"). The first is usually done between 7-9 weeks and the second two weeks later. If both confirm the first EDD (the one done at 7-9 weeks, which is the most accurate time, then that date is used.

Delivery dates are not exact because many different circumstances can influence when the actual delivery occurs.
