Ughh😷 help me.

my vaginal smell has been really bad during this pregnancy, ive had on and off VB, UTI, and yeast infection i wash daily and keep clean this is the first time ive dealt with this ever, my last pregnancy i dealt with yeast but not like this what do i do to prevent it. its making my sex life with my husband very diffucult and awkward. I've taken 3 rounds of antibiotics prescribed by the doctor and it goes away but I just keep getting it back. Do any of you mamas know of natural remedies that can help me out and that Is safe for pregnancy.

PS. I drink lots of water too and it doesn't seem to help either.
