I have been taking one 540 mg Black Cohosh capsule/day for about 2 months now. I am 51 years old and have not had a period for about 2 years until now. Prior to menopause I was having very heavy periods and was found to have uterine fibroids, which I chose to not have removed. Now I am having a very heavy period. I have been reading that Black Cohosh can act as an estrogen in our bodies. That is why I'm thinking my period has resumed. Would you recommend I stop taking the Black Cohosh, which has helped A LOT with the hot flashes? Should I consult my physician, i.e. could there be another problem going on? Thank you!
