It happens sometimes and is normal. If you feel it's too much, i'd recommend making an appt. W/your gynecologist immediately.

This happens to me also, im not too worried about it,though if you find out this is abnormal please let me know :-)

During a normal period, you pass from 1-3 tablespoons of blood. If you feel that you are passing more than that, see a doctor. However, clots are normal.
