PLEASE HELP

So im currently in hospital. On the 7th I had a cerclage placed due to my cervix being 20.9mm. No funnelling. Closed.

Today I can for my 20 week scan and my cervix is funnelling all the way to the stitch. Only thing keeping baby in is the stitch. I am 21mm with funnelling.

My doctor doesn’t believe the progesterone works so I’m not on bed rest as long as baby stays in

Has any got any success stories or advice being in a similar situation?
