What can I use for funky smell from the vagina?

Dr. can evaluate. A fishy smell coming from the vagina could be a sign of an infection called bacterial vaginosis. It can be treated with antibiotics that a doctor can prescribe. You might consider seeing your ob/gyn for a full evaluation.
Get checked. This could be a sign of bacterial vaginitis, which can produce a "fishy" odor. A simple check can usually figure this out quickly. Hopefully treatment will also be quick and easy.
Vaginal odor. Assuming there is not a serious infection, the odor has to do with an elevated vaginal ph. I recommend rephresh availabe over the counter and water works which you can purchase online.
