Vaginal odor

Hello. I’ve noticed vagina odor after my period. It doesn’t smell fishy it’s more like a pungent, sour smell. Has this happened to anyone before? Periodically I’ll have itching and burning with urination, no STD’s and I don’t have any weird discharge. My discharge doesn’t smell. Only time I notice a smell is after my period. Does it sound like my pH might be off? What do you guys recommend?

It’s kind of embarrassing. 😵‍💫
