Its honestly up to you but when my cervix started to shorten I made sure that I got the cerclage surgery. I wanted to make sure that i did everything in my power to save my son and if it did fail me at least I knew in my heart that i tried. Progesterone just wasn't doing enough for me now I am 31w4d pregnant with my stitch and its still holding my son idk if I would of made it this far without it. But it is solely up to you at end of day. Good luck
I think whatever your OB recommends. And of course whatever you want to do. How far along are you?
