i am currently using metronidazole vaginal gel that was given to me by Planned Parenthood. I have gotten BV three times. The first two times I have used the pill which did not help at all. I am now using the gel. The clinician told me to use it at night so the gel can soak up in my vagina. In the morning while I am showering, can I used my finger to clean out the gel? And what is the white stuff coming out?!
