Question by Mommy2be: During the first 5-7 weeks of pregnancy can a twin pregnancy be be mismeasured in terms of gestation?
..In such a way that the measurement of the gestational sac(because of size) would say that you are further along than you really are(if there were in fact twins)
PS...I don't know if I am having them, I am just curious. Ultrasound on Nov. 7th though
gestational sacs have to have a different range if they are looking at twins, right?
..maybe if they did not know that they were looking at twins?
