Risk4preterm labor? : Congratulations. You have already beat the odds by going beyond the point at which the miscarriage happened in prior pregnancy. It is impossible to state whether cervical incompetence is a factor without doing ultrasound study or seeing prior records. Report all concerns to your ob. There is an excellent university perinatal center in your state if you or your doctor want perinatal/mfm evaluation.
