Too much discharge?

Hey, I'm not sure if the discharge I'm getting is too much, but sometimes it feels like it's 'bubbling' out of me (sorry for the tmi) it sometimes smell vinegary, sometimes a bit fishy, and on occasion it smells of pee.

Ive a midwife appointment Friday which I will ask her. I was too embarrassed to ask her the last time, as I'm not sure is it to do with pregnancy or was it because I had unprotected sex with a friend not to long ago (another days story about that). So I was ashamed of myself to tell my midwife that as I know the dangers of unprotected sex and what harm it can do especially when pregnant.

Please ladies, id love some advice 😢xx
