Cramps on left side, no period, discharge heavy enough to be dripping down leg, hot flashes and nausea. what could it be?

See doctor: If you have so much discharge that it's dripping down your leg, it's possible that you have an infection or a std. I would make an appt with your family doctor or gynecologist to have an exam and determine if there is a vaginal infection. Hot flashes and nausea may not be related at all to discharge, unless, of course, you do have a std. Be checked soon, good lukc.
