After an emergency stitch placed at 19wks with my 1st pregnancy I still had my twins at 24wks..

This pregnancy I had a stitch placed at 14wks. Scan showed at 16wks everything was good, stitch in place and cervix still long and closed. Yesterday I had my 19wk scan and my cervix has opened BUT only to the stitch, so at this stage the stitch is doing it's job.. I didn't have an OB appointment yesterday, but the registrar I saw quickly,said I have a high risk of pre term delivery advised bed rest until I see the OB on Monday.. I have also been on progesterone pessaries since 16wks. My goal is now to get to 28wks. I also have placenta previa, I knew that from when I had the bleed at 10 and 12wks, but yesterday I was told my placenta is still covering the cervix.. Anyway...

I would love to hear anyone's experiences. I want to know things like: Did your cervix open at all like mine or stay closed? Did you still contract? When did you deliver? Were you on bed rest and if yes, when and for how long..

Thanks in advance..
