I started bleeding a week and three days early from my period. It started off lite and got heavier. It would go lite and heavier throught the day. It's been right days now and I'm still bleeding. My initial period should start in two days. I took a HPT and it was negative. Could I be pregnant or something else wrong? The day before I started bleeding I got real nausea after eating toast but never again since then. Breast are tender and been a little emotional. I'm also on birthcontrol and highly sexually active with my boyfriend and we don't use condoms. Please help
