My husband and I went to the Dr Friday and were told we were having what they call "mono-mono" twins. We were referred to a specialist nearby, but our appointment is scheduled for 2 more weeks. Last night, I started looking up what that meant about our babies and now I'm scared to death. I feel like we need to see the specialiat sooner. We had a miscarriage at 8 weeks back in September. At our sonogram Friday the babies were measuring 9 weeks and 8.5 weeks.....about a week and half a week behind. Their heartbeats were good too!!! Anyone else have experience with momo twins?
