Welcome and congratulations!
I know you're tired of hearing that, and so was I.
I'm not sure about whether or not the level 2 could be wrong, but I've read several posts on here where they didn't find a membrane until 15 or 16 weeks at a Perinatalogist, so I won't say that it's not possible.
I found out at 15 1/2 wks that there was not a membrane, and I had the same reaction, as we all did. I cried for days and just wondered daily if they were ok. I know everybody tells you to be positive, and I'll agree and say the same thing. Try your best NOT to focus on the negatives and really only read the positive success stories. I tell you, they really helped me! I have finally come to the conclusion that until 24 weeks, there is absolutely nothing I can do but keep myself healthy and take my vitamins for my girls
You will find MANY success stories on this site that will give you hope. If you believe in prayer, pray hard. I'm leaving the safety of my little girls in God's hands, because I know that I have no control at this point.
The odds of 50/50 are so outdated, and are much higher now with monitoring beginning at 24 wks. The facts that my Perinatalogist gave me really put the odds in my favor. He said that in his experience that out of 200 mono babies, that 140 will go home. I'll take that as good news! I surround myself with positive people who believe that this pregnancy will go great, and believe me...it rubs off on me! I become more and more optimistic at each of my dr.'s appts. when I see my little girls' heartbeats.
You'll find tons of support on here, and you'll get your questions answered. It's a wonderful site for support and encouragement!
Best of Luck to you and SMILE!
You're a twin mommy already
