My friend said her vagina smell like spoil milk & she has stomach cramps could it be bv? d/c yellowish greenish &can femine wash get rid of the smell?

PID? See doc ASAP: BV could cause the discharge and odor. But abdominal pain plus discharge suggest pelvic inflammatory disease (fallopian tube infection), and BV often accompanies PID. Yellow-green discharge suggests possible STD (gonorrhea, chlamydia). All together, PID is a good bet and she needs care ASAP. If can't been seen today by her doc or someone covering, go to ER or urgent care. DO NOT DOUCHE first.
