I'm 28w with my first baby and have a csec scheduled at 39w. I need a csec for medical reasons. I am nervous about going in to labor naturally before 39w because so many women have told me they didn't make it to 39w. I'm also concerned because I am a very small woman & I've been told at several ultrasounds that my baby is measuring big (90th percentile). Would that make me labor early? My mom had me at 30 wks and my sister around 36w. I'm afraid of that happening to me! Do most FTMs make it to 39w? I really want my Dr to deliver this baby because csec is a major surgery and DH and I are very comfortable with him. Any advice from other women who've been through this? Will the Dr move up my csec if I am having issues?
