My US at 19 weeks

Stina4242

So, my cervix went from 3.5 to 2.9 in three weeks.  The dr is not concerned about the measurement but how fast it changed.  He says that there isn't any reason to think it will become an issue (I think he was just saying this to make me feel better), but I am going weekly to have this checked now.

At our 8 week US the babies were only one day apart and now they are 5.  He is NOT concerned with this at all, I brought it up because it seemed like a big change to me.  My husband thinks I am crazy- he is probably right!

Anyone go through anything similar?
