BV again ...

So back in July I used metrogel for 5 days to treat BV, it never went away so now my doctor told me to use the metrogel for 10 days. The metrogel wrecks havoc on my lady parts!! I end up with a yeast infection and dryness. I feel like this is hopeless. I’m 30 weeks how will I ever get rid of this before I go into labor??!! Anyone experiencing the same problem??
