Like spade22, stated NORMAL. Just watch the size of the blood clots.
NORMAL!
Blood clots are normal during a period but shouldnt get any bigger than the size of a quarter - if they do, you need to see a doctor. Incidentally, it may take awhile for your periods to regulate so dont be surprised if you miss a few, alternate between light and heavy periods, and the clotting changes from period to period (i.e. sometimes you might not have any clots, other times you might have a lot).
