I ve had a very strange smell from my vagina lately. I had my menstrual in January, then only again in April and now only again in Beginning of July. My Husband and I had unprotected sex, but the pregnancy test came back negative. my menstrual cycle is not normal. for a week now, i had itchiness, burning and very comfortableness in and around my vagina. It is a awful smell, almost like a deadly smell. should I start to worry and do tests? I am very shy and afraid. PLEASE HELP!!
