How long does cramping last after my endometrial biopsy?

A few hours: Cramping should only last a few hours at most. This also depends on if your cervix needs to be dilated in order to obtain the biopsy. Taking an anti-inflammatory medication prior to the procedure may also help reduce cramping.

It depends: Pain is a very individual thing, so it is different for everyone. For the average person, cramping after an endometrial biopsy might last 12-24 hours. If you are in severe pain, or if your cramping is lasting longer than that, you should see your doctor.
