I had a keep procedure done 2.5 weeks ago, and have bled since. It has been much, much heavier than my normal period, but not filling a pad in an hour. More like 3 hours. But the last couple days I have had bad cramping when I try to lay down to sleep. Is this normal?

While the bleeding can continue for several weeks, generally it shouldn't be much heavier than a normal period. If it continues to increase in amount, and/or your cramping increases, best to let your doctor know. When in doubt, give them a call. The peace of mind is worth it.
