Yeast infection??

Okay so i don't know why but i feel like i might have a yeast infection , i don't itch or have a foul smell nor do i have crazy amount of discharge. but sometimes after sex there will be a quick fishy smell but it goes away and i wont smell it anymore , and i don't smell it when i insert my fingers into my vagina. also my mans penis doesn't look normal anymore is it possible that men have a yeast infection ? and if so wouldn't he had to have it a while for it to mess with his penis ? His penis is kind of inflamed like the skin on his head is all weird like almost as if he wasn't circumcised. I never had a yeast infection before but i read that it is common in pregnancies, we had a lot of problems in our relationship he cheated on me twice i left him and moved far away. now before i left and the cheating his penis was fine looked normal and after we got back together it looked like how it does now. and when he used to send me pictures before i moved back he would always cover his head and i always asked him why he did that. anyways we had sex when i got back but once i noticed his penis i got tested and i didn't have anything but his penis is still like this after like 6 months could he have given me a yeast ? Mind you before i moved back i got checked even though i wasn't having sex and i didn't have no yeast or anything now I'm pregnant I'm 3 months so now im really worried my obgyn is not open on weekends but i also have my appointment on the 25th for a pap smear so I'm thinking to just wait till then to ask if she can test me
