Womens health question?

i was wondering how early some women can go through the menopause, just that i have PC OS so ive always had irregular periods, but lately i have had them regularly, about a month ago i got extremely hot for no reason, this has happened a few times, also haven't had a period since 1st august but im not pregnant and use the mini pill, im 29 is it possible im going through menopause already?. my mum was 33 when she went through it but then she had, had 7 kids and ive only had 2, any help please
