I'm hoping someone can give me some advice/opinions. I always have a 25 day cycle and always have a migraine either the day before or day of my period and some light-moderate cramping. I'm never late, but this month I was 6 days late and sure I was pregnant even though all hpts were negative. At 6 days late, I had cramps and bleeding (dark brown/dark red, but mostly brown) which started at night and went through the next day. The cramps were only that night and the next morning. In total, the bleeding lasted less than 2 days. It didn't look or feel like my usual period, and I never got a migraine. Is it possible that this was implantation bleeding and I may be pregnant? I may test again in a few days. For now, I'm tired of seeing negative.
