PH Balance

I am 32 weeks pregnant today and for the longest time like for months by PH has been off majorly! It is so embarrassing I take showers at least every other day and I have told the OB doctor every time I go they check me out and everything is fine but any suggestions on how to level it out I have been eating yogurt and everything I just don’t know what to do and am tired of the smell it’s like dirty feet or something 😩
