Ever since adding turmeric to my diet, my periods are off. i was late once, now i'm very early (day 17 of cycle.) could this change be the turmeric?!

Early menopause: Early menopause is more likely to cause a change in cycle pattern than having added turmeric to one's diet. Stopping the turmeric for 3 months may help establishing the diagnosis.

Maybe: Tumeric can affect your blood's clotting function and though not well studied, there is some evidence it could affect your periods. To find out, stop it for 6 weeks and see if things go back to normal. Or not! Best wishes!
