acidic smell?

i recently started taking vH essentials cranberry probiotic pills and i notice that ever since i started taking them i have a faint acidic smell, not overpowering but if i touch down there i can smell it on my fingers. i take this in order to avoid smells, i drink lots of water daily too. any advice on what i can do to rid of this? *no itching, recently visited the gyno and no infections. pee is clear. not sure what it could be.
