6mm, Short Cervix

Update: Going to get another evaluation today, hopefully cerclage.

I went in for my 20 wk anatomy scan. My OBGYN told me I would need a cerclage and would be put on progesterone for my short cervix and basically be on bed rest. I had to go to a larger hospital with high risk doctors for the procedure. When I spoke with the doctors at this hospital they basically just explained to me how progesterone works vs cerclage. I decided to go with the progesterone because the way they explained it was that they are both good preventative measures for preterm labor, but I would only do one. Cerclage seemed higher risk to me and since they were both effective progesterone seemed safer for the baby to me. I started the progesterone Thursday night and will go back in to get checked on Monday.

I was just wondering if other people had a very short cervix of around 6mm around 20 weeks and able to carry to 36wks with just progesterone. A lot of post I’m seeing are like 15mm-23mm. This is a singleton pregnancy and I’m a FTM. They also said my cervix is closed rn which is good. My pregnancy thus far has been pretty smooth, just headaches.
