Thanks for the query,
Puerarai Mirificais contains estrogenic phenol.
Continuous and constant exposure of the endometrium with estrogen results in increased endometrial thickness with withdrawal bleeding which is quite heavy.
At the age of 53, its not normal to have heavy bleeding though there are few exceptions.
Do get your USG done for endometrial thickness.
ET>4mm is considered to be risk factor for endometrial Ca.
You are less likely to be pregnant as ovarian reserve
at this age is usually minimum.
hope this helps.
