I had sex 2 weeks ago and I toOk Plan-b less then 12 hours later. Then I was spotting semi heavy, enough to use a tampon for a few days, and no I have noticed a strong unpleasant odor. I have never had issues with my scent or vagina and also I know the person is clean in that department. Now I am under a great deal of stress and pressure and was wondering if that would be it. Please help me! I am freaking out!
