Post Menopause Bleeding After Cramps Like Ovulation Cramps

I had what felt like ovulation cramps last week and tonight have vaginal bleeding, fresh blood not old.

I did this in 2012 after my mom died, was checked pap smear, uterine biopsy and I feel those hurt, it was all good, they thought it might of been stress related because it lasted only one day.

My abnormally normal periods were only 1-3 days, they were one coming in, one day of heavy bleeding, and spotting on third day. But every 28 days like clockwork with no issues there. In my 20's I was told I had endometriosis and when they went to do the ultrasound the cyst had went away. I didn't take it any further than that but never had children and never took birth control. Cramps were always very painful, had to curl up in a ball, always had severe back pain with them as well.

Last week they were like that not quite as bad but nearly.

Is this just a fluke you all think? Even menopause I had no symptoms, when I turned 50 it shut off like a faucet never again until 2012, and now.
