I'm not sure I would trust a doctor who didn't pick up on twins by 37 weeks...not sure how you could miss it with a quality ultrasound :)
But definitely post after you give birth so we will know for sure! I did a quick internet search for missed twins and didn't find any follow up posts saying what actually happened for those that posted a question similar to yours...and no confirmed surprise twin stories after having at least two ultrasounds that I saw...
Early ultrasound can miss twins...but later on they get kinda hard to not see...
im in the same position. Im feeling what seems to be 2 babies in there and have heard what seems to be 2 heartbeats on the doppler during my non stress tests. It is not unheard to know of a dr missing a twin. Ive heard it alot even with ultrasounds, my dr still says im only having 1 but nobody has looked for a twin. Im 34weeks and 3days. Dont worry, your not alone.
I'm 12 weeks and my Dr can't miss my second baby and he would have picked up a second heartbeat by now....
no there isnt a chance if you have had ultrasounds. why do you think you are?
