I'm not a doctor, but that seems pretty normal to me. The clinic told me I would bleed 2-4 weeks. It finally stopped about a day after I found this forum, which ended up being about 4 1/2 weeks after I took the pill. I even went to the emergency room around 3 weeks. It had lightened up to about what my normal period is. But then one day I filled about one pad every 2 or 3 hours. And I started passing kind of large clots (prune-sized). I freaked and went to the ER, but the doc said I was just still passing the leftovers. And everyone on this forum seems to have similar experiences. Pain and REALLY large clots appear to be the only real sign of trouble. But if you still feel wary, see a doctor. It can only help.
