I would get some oral tablets such as nilstat or diflucan one. I personally would feel funny about inserting anything while bleeding.

The pharmacist will have coniptions about giving diflucan to you while breastfeeding but a study done by a dr at the royal women's showed it had no side effects on baby (and I personally took three courses of nilstat oral AND about six diflucan and bub was fine). The study was about thrush in lactation relating to breast and nipple thrush, but the internal treatments are the same.

Are you in Melbourne? The royal women's has a clinic you can go to and they can give you cheaper prices on the meds.

Otherwise look up thrush in lactation Royal women's hospital and read about it.
