Mono mono. Possibly conjoined twins.

Last week we had an ultrasound at 8 weeks and we’re told congratulations it’s one baby!! My Dr asked me to do a follow up this week and I assumed it was because we had a loss last year from a complicated pregnancy. Today we found out there are twins (mono mono) and got sent straight to mfm because they possibly look conjoined. The mfm couldn’t confirm and is having us come back in two weeks. Any other mono mono moms out there ?? This is a lot of news to take in!! Also we already have 4 1/2 year old twins ( natural for both ) so that’s a big shock on its own !
