Hi
Just wanted to say good luck next week! I had a cerclage for my last pregnancy and delivered my DD safely at 38 weeks when the stitch was cut for delivery. I am now pg again and will get another one when I get to 14 weeks. I'm in Sydney so can't comment on your hospital but thought I'd share my experience.
Unlike Crumpet, I had no antibiotics or meds at all when my last stitch was put in and was only in day surgery. I also was under GA for the operation as that was how my ob preferred to place the stitch and that was fine with me! I had no bleeding but quite a lot of cramping after the procedure which had me taking panadol and using the hot water bottle for a few days after but once that eased I didn't notice the stitch at all for the rest of the pregnancy. I had no swabs at all (except the routine strep one at the end) but did have regular internal u/s to monitor my CL and ended up spending 3 weeks in hospital on bedrest from week 21-24 of the pregnancy due to shortening of my cervix. That was hard I won't lie, but obviously all worth it. That was the only time I was placed on AB's and that was precautionary while in the hospital.
All the best with the procedure and I'm sorry to hear of the loss of your sweet babe x
