Oh I had exact same thing I had oral, vaginal and nipples and dd had oral and was starting to get vaginal cause I was on antibiotics due to a bit if retained placenta so I had light bleeding

I didn't actually think to ask if it was ok so I'm not sure if it is so I did it but I had no issues and it cleared up the oral thrush on the other hand took ages to clear I found using the nil stat and brushing my tongue everyday sped up the recovery but it was yuk to have

If your bit breastfeeding you could take the Canesten pill I think that does it all
