It could be bacterial vaginosis (BV). It usually causes a fishy odor especially after sex.
like the person above it is most likely BV and causes a fishy odor. But it is very treatable and not an STD it is the second most common issue women have next to yeast infections. it can also cause slight irritation during sex, can cause darkening of urine with the odor. Unfortunetly I get it on a regular basis and Doctors can't explain why. try acidpophulis which is found in most health food stores, and in some stores with the vitamins. But go to the doctor and the will most likely perscribe flagyl which an awfull tasting anti biotic 500mg twice a day for seven days. I hope this helped
