I need someone 😭

So my SO and I have been trying for baby # 1 and I have noticed that his semen makes my vagina smell like fish. I didn’t know if it was for sure his semen making me smell like that so when he went off working for a few weeks the smell didn’t come back again, then he got back home yesterday and we did it, I wake up today and my vagina smells like fish again. So I talked to him about it (it took everything in me to tell him my vagina was smelly) I told him he is gonna have to start eating better and we are both gonna start taking vitamins, and he got super pissed off at me for telling him that his semen is what was throwing my Ph balance off. And he started trying to make me feel bad, I was not trying to hurt his feelings in any way when I told him he needs to start eating healthier. I just don’t know what to do now. So now he’s like “ohhh nooo, it’s okay, I just won’t cum in you anymore.” He hurt my feelings so bad, I had to go to the bathroom and cry.
