Does anyone else have this happen?

TMI but when me and my boyfriend have sex ( i feel insecure being in my third trimester and looking like a whale already) when we have sex and when we’re done i notice that there’s thick cottage cheese looking discharge around his penis it’s not a lot but it’s coming from me , from inside of me. It doesn’t have a smell but after sex i burn a little bit. I have gestastional diabetes so i know yiest infections are gonna be common
