Some day around October 10th i had protected sex and i am on birth control, about two weeks after that I had different discharge as well as occasional itchy and painful vagina. It become heavier and kind of thick than normal, and started to smell, I guess you could call it fishy. But then it became more like a liquid still heavy, to the point of it going through leggings i was wearing onto the seat. I had felt uncomfortable sitting close to people because I could smell the odor. Eventually the odor stopped. I got my period two days ago and went to the doctors but they told me to come back once it has finished. Today it hurt when i peed and later i noticed that my period blood had a gross smell to it. It wasn t the same smell as before, but it was gross. Also there s a small area around my vagina that stings. What s happening??
