I have no clue what's going on. So randomly my vagina is swollen and painful. Last time I had sex was probably a month ago. Seems like it's my urethra. It's painful. No smell no weird discharge except I just started spotting (I was on depo and haven't had my period back yet) but it's all red and swollen and itchy. And when I had sex it was protected. Idk if it's a yeast infection or just urethritis. Help!
