If you have a permanent stoma and your doctor thinks that you have a rectovaginal fistula
, the first thing that you need to exclude is a recurrence of your cancer as such a fistula should not normally form in the presence of the stoma. For that you should get a Positron Emission Tomography
(PET) scan done. If it is normal only then should we be talking about pregnancy
, else you will have to start on treatment for the recurrence. To answer your question, a rectovaginal fistula will definitely affect your pregnancy as it is a constant source of infection to your vagina from where the infection is likely to ascend to the uterus leading to a number of complications like miscarriage
, infected liquor, fetal distress
etc. It is not advisable for you to get pregnant till the fistula is taken care of.
