BV & yeast infection ....

I keep getting bv & yeast infection go to the doctor every time take the meds it clears up but comes back after a month it’s driving me nuts! Has anyone else has this happen?? If so have you found something that has stopped it from coming back?? I just had my baby girl in December before getting pregnant I kept getting them then while pregnant they stopped until the end of my pregnancy now it’s started again so sick of dealing with it.
