Hi girls)??? I've been admitted to the hospital again. At 17.5 weeks my cervix is already 18 mm, so I think they'll stitch it tomorrow. But the thing is, they've prescribed suppositories to start inserting from today. I read online that pregnant women aren't supposed to use them, but the doctor says that with these suppositories something will improve and they can operate tomorrow — and that without treating with these suppositories they can't stitch ? The name is TERZHINAN, has anyone been prescribed these?
