This is kind of gross, but...ladies help!?

I took my last dose of monistat 7 today, my yeast infection was gone with the third but like the box said, I finished all the doses...tomorrow im going to my boyfriends apartment and he has this obsession with performing oral on me. Is it safe to do?...i dont wanna be like "hey, dont go down therw, I shoved some yeast infection cream in there yesterday". What do I do? Thanks..
