Monochorionic Monoamniotic Twins (MCMA)

Katie
So the dr said my twin could be MCMA twins..... Has anyone else been through this type of pregnancy? I've been looking up a lot of info online and I'm kinda worried 😞 Drs didn't seem that worried though.... Idk what to think... Advise please. Ps the US is at 7weeks 3 days, both babies are measuring the same and have heart beats in the 130s I'm currently at 8 weeks
