Metronidazole vaginal gel

Janny
Hey guys 
Was wondering if anyone was diagnose with BV and given the metronidazole gel ?
I went to my doc on Tuesday and was diagnose with both BV and yeast infection and she ask me to use metronidazole gel first for 5 days and on the 6 day take the pill for yeast infection
Today is my 3 day on the gel and I have some cottage cheese like brown-white discharge when I wipe . I'm freaking out 
Help !!
