Thanks for your question & the detailed history.
If there is no period for 1 year we diagnose menopause
. This bleeding after 2.5 years cannot be taken as your periods. We take is as post menopausal bleeding which need evaluation. In 10% of cases it may indicate serious genital tract pathology like cancer. So, please consult a Gynecologist for full evaluation.
All these may represent an effect of your natural therapies. But evaluation is a must.
Wish you good health.
