one thing i'd like to highlight from this link is the following. The woman who just safely delivered her triplets was at first told that she has mono twins, but, in fact, she didn't. It took repeat u/s w/ other drs to determine there was a membrane separating them.

"Are they sure they're in the same sac?
What may be the best news of all is that the amniotic membrane can be very thin. So thin, that's it's extremely hard to see on an ultrasound. So misdiagnoses are common. If the diagnosis was made before 8 weeks, it is definitely not certain. It is simply not possible to get a reliable determination of whether a membrane is present or not before 8 weeks. After that point, there appears to be a window around 10 to 12 weeks where the membrane is easier to see. Others note a window at 16 to 20 weeks. So if you are diagnosed before that time, you may want to ask for a repeat ultrasound during one or both of these timeframes. However, what appears to be far more important in accurately determining whether a membrane is present is the use of a high resolution ultrasound machine. Many times, and OB will refer a patient to a specialist, convinced the babies are monoamniotic. But often with the aid of a higher resolution machine, and years of high-risk obstetric experience, the specialist is able to find a membrane."

I talked to my mom and my twin and I shared one sac and one placenta and we came at 38 weeks and we were both very healthy.
