You may or may not have bleeding. I did not have bleeding with either of my ovary removals. It just depends on your body. If you are soaking a pad every half hour, then you need to get to the ER because you could have opened your internal stitches. Bleeding can last for a week to a few weeks (should just be spotting after a week or so). Are you bleeding, or just anticipating it?

It varies by patient, where you are in your menstrual cycle, etc. It is only considered "bad" if you soak a super absorbent napkin every 1/2 hour or so (that is excessive bleeding that needs medical attention). I would say the bleeding is probably more than a normal period, though, and perhaps for more days than average.
