I suspect I may have this. My mum has PCOS (not sure if heridatary or not?)

These are my symptoms:

- acne around chin and jawline (hormonal i believe), also sometimes cheeks (only since coming off the pill - 1st few months was fine but now im getting acne all the time)
- although im not someone with a lot of hair at all - i have noticed some more than normal
- periods since coming off the pill in june 2009 range form 30, 35 and 40 days - so they come but they are irregular
- i have put on 10-15 kilos since coming off the pill (is weight loss a symptom or a cause??)

I am getting really down on the acne and weight game and it is annoying with my cycles being a little all over the place. I would be grateful about whether you think i may have PCOS?

TIA
