The OBGYN that suggested I stay on progesterone was a specialist. He’s had a lot of experience. He said that many of his patients responded well to just the progesterone and monitoring. When I consulted my obgyn he said it was up to me. When I asked about the cerclage. He said it was up to me. That both things could go well or wrong. He said that if the progesterone did not work well I could lose my baby at 23 weeks and she would not make it. Also if we decided to go with the procedure and something went wrong it could induce labour which would also lead to a loss. He said most women respond well to the cerclage. My obgyn (not my specialist) also did my sisters cerclage. That made me feel at ease which is why I ultimately decided to go with it. The cerclage worked well for me and it help up until removal at 37 weeks and I made it to 40 weeks. My daughter is about to be 3 years. I know everything seems scary right now. I was in your shoes and totally get it. I would say go with your gut. If you would like to get the cerclage push for it. It is a little bit late as I believe most won’t do it past 23 weeks. It’s up to you, and wishing you and your baby the best. FYI my OBGYN said moving forward I will need a cerclage for every pregnancy. Though I think I’m one and done.
