Spotting, need advice please

Hi everyone, I’m new here and seek advice. I’ve been menopausal for 12 years and in early December I noticed spotting when I wiped. After a couple days, it stopped. I went to my gynecologist and she saw that there was some blood when she internally checked me. She did a trans vaginal ultrasound which didn’t show anything suspicious. but a fibroid that I’ve had for many many years. She told me the uterine lining is very thin so there isn’t any concerns. I followed up in 6 weeks. There was no bleeding and ultrasound did not change. she told me not to worry and she would see be again in 1 year for my annual checkup. My question
