Yeast Infection? Or??

I’m usually not the type to ask questions about my vagina. I’m pretty knowledgeable about it, I know my cycle, good and bad smells, etc. but this one is catching me off guard a little bit.

I’ve been off BC pills for months. I’ve been told that I “smell bad” down there. I thought it was just something I was eating, but I haven’t changed my diet at all since before it started smelling “fishy”. It’s been like this for about a month or so now. It’s beyond embarrassing whenever my boyfriend and I are trying to get in the mood, especially when he wants to eat me out but in my head I’m so afraid he’s going to spit it out. He never does, but it’s a fear of mine now. He says that he doesn’t mind it and that he knows I can’t control it but I know he does mind. And I want him to say “damn you taste good” and not “it’s not terrible”. Like... ugh😭 it’s so embarrassing...

My question is: I just recently started my birth control again (a week ago). My vaginal smell has somewhat improved, but not very much. It started being itchy a few days ago but not to the point where I couldn’t stand it. But it keeps itching, sometimes I literally have to stick my hands in my pants and scratch the opening into my vagina. Could this be the start of a yeast infection? Or could it be my hormones trying to rebalance?

Note: I have been exercising a lot lately and don’t necessarily change my clothes right after. But I’ve played soccer for 14 years and have never had a problem from it.
