I'm 45 and have normal periods. The only change is that 3x, each about 1.5 years apart, I'm had crazy bleeding episodes between periods. The first two only lasted two days, but the last one was two weeks....and I mean A LOT of blood. I've been to the doctor and they said it was
called this and related to my age and because I'm probably randomly not ovulating some months, which causes the bleeding.
