BV vs yeast infection

Whats the difference between the discharge produced by these twos. My discharge is really thick and white, sticky, doesn’t really have a smell. I did have unprotected sex three days ago, and haven’t gotten my period in a while. So I’m not sure it’s one of these, I’m just curious if this discharge has any symptoms of something. There was a lot in a short span of time, more than usual. He did cum in me the day we had sex, so maybe he threw off my ph balance? Idk...
