So your experience might be different, but these made my very on time period start 5 days early and made it last longer than noraml and terrible Cramps. I realize that this might have been attempting to adjust things....but I don't pcos, I took them because I heard they could help with a lot of different things, hair growth being one of them. But I stopped taking them after the craziness period ever (it seriously was starting over again on day 5 which normally it would be completely over then....)Again your experience might be different and it may help u.*It did help mom to lower her blood sugar some(she is diabetic and trying to deal with it naturally). But it does make her tired, which is a common side affect if you look into it.
