Other medical history included Hypertension, anaemia, and stress disorder. So basically from 24Jan2022 to 05Apr2022 she did not have a period and at her old age of 48 her periods were regular. Definitely was not pregnant. Not going through menopause (been did all that testing) don't have fibroids or none of that and let me just say as of today 24Apr2022 she had been on her period for 20 days since 05Apr2022. This had caused her to have severe anemia and even with medication like medroxyprogesterone 10mg it was not stopping.
