Pregnant with Mono-amniotic twins!

Hey everyone! So yesterday me and my partner found out we are expecting identical twins, measuring at 12 weeks 2 days, both perfectly healthy but they do share the same sack and share the same placenta. So I know how rare and high risk this twin pregnancy is. I’m only 22, I have a 2.5 year old little girl and I am absolutely terrified! Just seeing if anyone on here has momo twins or looking for a little support I suppose! Thankyou
