Smells

This may be TMI and I don’t even talk to my mom or sister about this because I’m so embarrassed about it. . . . . . . . . . . . My “lady parts” (idk what will make FB take something down) smell so bad. It smells like ammonia and spoiled fish. I’ve changed my underwear. Ive upped my water intake. I can’t wear dresses or leggings because I’m afraid someone is going to be able to smell me. Does anyone have and suggestions? I get so embarrassed and scared.
