Unusual odor after amoxicillin.

I finished ten days of amoxicillin two days ago. Around two days ago I noticed a sudden and unusual smell while using the bathroom. It’s almost like a moldy bread smell, if that makes sense. Kind of ammonia too. I don’t really know. I do know I have no change in discharge or vaginal smell. It’s more concentrated around the top of my vulva. I have no other symptoms. No itching or burning. Nothing. It kinda comes and goes, but it’s basically always there. It’s not possible to have an sti. I don’t have a yeast infection. I doubt I have bv since the smell isn’t from my vagina. Has this happened to anyone else?
