I've been bleeding for 7 days before my period should've started. I'm having stomach pain and lower back pain. I feel sick every morning for the past couple of weeks. I seem to have every symptom of being pregnant only my home pregnancy test came up negative, could it be too early? Or could something else be wrong? I have 3 children now and have had a miscarriage.

Are you saying you DO have your period now but you also have stomach pain, lower back pain, nausea?

Just so I understand -

Sorry to confuse you Im confused to I've never had an early period, but started bleeding 6 days before expected. Not even regular for my period. I've had extreme stomach and back pain, trouble sleeping at night. I feel sick every morning. Im on my 7th day of bleeding now. It started very dark passed a couple clots the first 2-3 days then bleeding stopped for a bit. The bleeding started back but has been light pink to a brownish color

I would guess you are NOT pregnant. Of course, only a Doctor knows for sure.

Maybe your period was "simply" early? Is seven days normal for you or is it longer than usual?

Sounds like just a bad period BUT maybe you should get checked by your Physician?
