My period is always irregular -- so much so that I rarely notice when its late. So I honestly can't say how late it was or if it was late at all. But it started 2 days ago and was very light with no cramping at all. Then yesterday afternoon I started cramping. By about 9 p.m., it was so bad, I was rolling in bed...I couldn't eve lie still. It almost felt like labor. When I sat up, I felt what I thought was a HUGE clot come down. It was so big I had to tiptoe to the bathroom because it felt like a had a tennis ball between my legs. When I sat on the toilet, it heard a huge splash, and when I tell you the clot was huge, it was HUGE. It was about as big as the center of my hand (without the fingers) I have some clotting with every period, but NEVER this big and never all at once. it's usually a bunch of little pieces. The cramping stopped as soon as I passed it, and it hasn't started again. I am still bleeding though. Could I have had a misscarriage? The last time I took a pregnancy test was about a month ago.
