I took the morning after pill for the second time in my life a few days ago, and now I'm bleeding. It's pretty heavy. The side-effects I think is supposed to be spotting or bleeding. Is this normal, should I do anything about it?

When in doubt, always talk with your doctor.

Yes, it is normal. The MAP pretty much causes a miscarriage, whether you are pregnant or not.

If you are bleeding heavily then go to your doctor asap. Better safe than sorry.

It's not heavier than anything I've ever had, it basically seems like a period in-between periods, and that's all. I read the "manual" in the pill box, it says that it causes bleeding. It's lasted a couple/few days now.
