Has anyone experienced bleeding after a hysterectomy years ago and also have been thru menopause?

Could be a number of things but it's NEVER a bad idea to have it checked out by a medical professional. It could be something as simple as a Bartholin's cyst that ruptured or a bladder infection but may well be more serious.

Need to get to your gynecologist.

Call your doctor. Find out from her/him of you need to be seem immediately at an ER or if the office can get you in for an appointment quickly.
