I am 65 yrs. Of age, have been done with periods for 10 to 12 yrs. And now all of a sudden I am bleeding just like a period, this has happened 3 times now. I was given a Pap Smeer, it came back good, no problem there. Then I was put on Prevara for 10 day's, when the 10 day's were up, about 2 to 3 day's after I started bleeding again. What's going on here?

This is something to be diagnosed and treated by a Physician following a physical exam.

I'm afraid that anyone here who attempts to answer is only guessing without seeing you.

And, of course, it could be any one of a variety of things.
