I'm currently in the hospital for the 4th time for preterm labor. They did a cervical length check and that hasn't changed at all, however when they checked my cervix I am 3 to 4 cm dilated already. I've been on procardia for 3 days now and had last dose this morning. Contractions have pretty much stopped but I was on procardia every 8 hours. Has anyone had similar experience and when did you have baby? They want to keep baby in for at least another 2 more weeks.
