Vaginal Smell - maybe tmi description

Because of my recurring UTIs due to sex, a doctor prescribed me antibiotics. I was to take 1 at the end of each day that I had sex. Typically, I would end up taking about 2 per week. This lasted about 3 months until I went to see another doctor.

My new doctor recommended that I take probiotics for the urinary tract and d-mannose in order to prevent my UTIs. With this practice, I haven’t gotten any new UTIs so far.

I don’t know if it’s related, but after a month or two of taking the antibiotics, I noticed that my underwear would smell significantly bad at the end of each day. (I clean that area gently everyday and do not douche.) My underwear would smell of urine, look dirty, and contain more discharge than I normally used to have. Because I suspected that these changes were due to the antibiotics, when I started taking the urinary tract probiotics, I decided to also take vaginal probiotics for a month. During that month, all the symptoms listed lessened significantly.

Once I finished the vaginal probiotics, I decided I would stop taking them (because they are expensive). It’s been about four days without taking them, but all those old symptoms seemed to have started again.

I’m concerned. Does this sound familiar to anyone?
