My period was strange last month. Following it I was nausous, tired, and moody. I would feel over-full always! After I ate it would be quite uncomfortable. Now this month I had weird cramplike feelings in my ovaries weeks before I was even expecting my period this month. I was 4 days late and the bleeding started with brownish color had one heavy day an now practically nothing. These past two periods have been very unusual. I had taken 3 pregnancy tests and they came back negative. Is there still a chance of being pregnant?

Most likely no, but a trip to your doctor to see what could be the issue would be called for
