I am on my placebo pills of the birth control pill Aubra that I've been on for 8 months. I take my pills everyday. I had unprotected sex for 5 seconds and he stopped because I got too scared, no ejaculation. Now yesterday was my second placebo pill had I had light bright red bleeding, only used on tampon. Than it turned to a light brown discharge at night. This morning , there was no bleeding or discharge? Was this my period? Or am I pregnant? Maybe my period will start up again?
