recurrent vaginal infections after nexplanon removal?

I've been off nexplanon for three months. I got my period the moment it was expected to come & thought I ovulated right after.  Now I'm starting to think its bacterial vagionis instead of ovulation? My period has came every month so far, just shorter than what they used to be 5 or 6 days instead of 7). A few days after my period I get an increase of a milky white thin discharge, my vagina feels very tender, dry, & there has been times when it had no odor and times when it smelled fishy. Also whenever I'm touching it, rather it be with my fingers, cloth, or a tissue it feels as if I just ate flaming hots or peppers and touching the outside of my vagina without washing my hands. Also, may I add it's not the inside it's the vulva, clitoris, and the monis pubes. The inside of the vagina just releases the discharge which if I let it sit there long enough it'll cause mild discomfort, no immediate urge to itch or no burning while peeing. I can even have sex without a problem. Every time I think to make an appointment at the doctor the symptoms go away then come again the next month. Does this sound like bv? Although I've been sleeping with the same man for the last two years. Has this happened to anyone else? Also, may I add I take feminine probiotics almost daily.
