Anyone been through preterm labor, bedrest, and taking procardia? I'm still having contractions mostly at late night or early morning. I guess my question is if the contractions aren't completely stopped could she still wait a little longer? I'm only 28 weeks and want her to wait but how I've been hurting makes me think she may not wait. I've on my second bottle of meds. Does procardia ware off after you been on it for a few weeks?
