Cervix thinned

bjgonzales1217

So I just have a quick question.

I'm a high risk pregnancy with a gastroschisis baby. They are monitoring me weekly with ultrasounds and NSTs. Last week, when they checked my cervix I was 3 cm long, normal length they told me. Today, a week later, they said it went down to a 2 cm thinned, and if it goes below a 2 then they will start me on shots.

I am 30 weeks and 3 days pregnant now and a lot gastroschisis pregnancies do not go past 35 weeks (what I've heard) and they have me scheduled for an induction date when I turn 37 weeks. Is it normal for a 2cm thinned cervix at 30 weeks? Just looking for a few others with this

Tia!
