Thankyou both for your replies, I guess its just a wait and hope thing.
I highly recommend getting the stitch. My first pg was early, second on time, but this time around my cervix is feeling quite open and I think I am going to have this procedure done once I get a BFP and am far enough along. Quite simple procedure, low risk. Go for it!
I think this is standard of care for an incompetent cervix. I'm sorry you've gone through so much. My friends sister in law had the same diagnosis and had premature babies as well (twins which just worsened the condition). There babies didn't survive. Heartbreaking. They are now pregnant again after taking a year to mourn and all is going well. I know that this couple also said that in the future they would see a high-risk OBGYN who specialized in high-risk pregnancies and can make better recommendations for you.
