on October 2nd I was supposed to start my period, but I had brown watery discharge instead that turned to very light bleeding, and now is enough that I need a pad. So 5 days now I've had it. I took a test, negative. It burns when I pee but that started before the discharge, and now I have a bad constant lower back ache, off & on cramps that are low down, and right under my breasts my stomach is sore to touch. We've had unprotected sex for a month now TTC, but this doesn't seem like a pregnancy to me. I have a doctors apt at the gynecologist in 3 days.
