Bv. Bacterial vagnosis and conceiving

Me and my husband have just started trying for a baby for the last 2 months. (No condoms no bc) this is also the first time I have let anyone cum in me. Hear lately my pee smells really bad and cloudy and burns a little. Went for a check up and they said I didn't have a uti. I have another check up Tuesday. I was wonder if I could have this from him cumming in me. The doctor previously had told me my ph was very acidic and wasn't sure why. Please help! I'm freakinf out because I don't know what to do and it's so frustrating when doctors don't know why. Just curious if I could have this bc I does smell really bad especially in the morning and I drink tons of water throughout the day. And I thought my discharge was cm but idk if it's that or discharge from infection.
