she was on it since puberty to regulate her menstruation, years later she was diagnosed with pcos
That's strange. as far as I know, it is common for periods to be irregular in your teens, and take about 5 years or so to regulate (so if you get your first period at age 12, you'd be 17/18 by the time it got regular), at least that's what I read in all the health pamphlets/magazines/was taught in school and all. I got my first period at 10 (early I know :() and up until last year, it was regular from age 15 and onwards.
god knows...but hers used to come every two weeks and all the alternative health docs told her, it was the pill she took in early days of puberty that caused her acne, pcos and weight probs
anyways i highly recommend b100 complex for fertility issues
