A member asked:

I thought i would be 8 weeks and 4 days pregnant by now based off my lmp but when i got a transvaginal ultrasound done my gestational sac was measuring 7 weeks and my yolk sac was measuring 5 weeks and 4 days. i concieved on november 20th is this ok?

Estimating the gestational age is not an exact science. Go with the estimate based on you LMP. Please note that even the best estimate will have an error of 2 weeks either way for the delivery time. Get regular antenatal checks. Wish you good health and a healthy baby!
