Yep there are potential negative effects of c-section to read up on; including not receiving the benefit of mum's vaginal flora to help build a healthy gut, and there are higher incidences of respiratory problems in c-sec babies. Lots of progressive info out there if you have a google.
Also, if you are only 32 weeks, how can your doctor be sure the cord will still be around bub's neck in approx 2 months time? Will you have further scans to confirm it?
Probably good to talk to an Ob as pps have suggested - a general practitioner really does not get much training whatsoever in pregnancy or birth.
Good luck, OP.
