Weird smell vagina?

So I went to pee first thing In the morning and I smelt somethin and I though it was my pee Bcs of something I ate last night maybe ? And then I wiped and everything looked normal but my vagina smelt a bit off. Kind of like apple cider vinegar. I fell asleep last night without showering so I thought it was just that but it smell like a sharp acid not fishy or anything I’ve been drinking apple cider vinegar a bit too for a couple weeks. My period is in 4 days too.
