Pre-existing fistulas's and abscesses

Hi, I'm not expecting many people to have had this but it worth a go! I have suffered with multiple perianal abscesses and fistulas for 10 years now I have had 9 bouts of surgery to remove the fistula in my bowel 6 being in the last 2.5 years. I'm now 29 weeks pregnant and I'm having a real battle with my consultant to agree to a c-section,due to the fact that childbirth can cause fistulas and I honestly don't think my bowel can take the pressure without re-infection occurring .Anyone else had these issues?
