C.O.
I know most doctors like to "label" this as PCOS - polycystic ovarian syndrome.
However, I would SERIOUSLY use caution before getting "lumped" into this category of labeling.
Have your OB/GYN do a thorough exam - hormone levels to include testosterone levels, estrogen, etc. blood count - the WHOLE thing...DO NOT let them LABEL her and put her on the pill....
I was 15 when I got put on the pill - mine were VERY irregular, I have a deeper voice, etc. PCOS was NOT around when I was 15 so they just said "here - take this" and it worked - I stayed between 135 and 145 and my periods came one per month like clockwork...the minute I got off the pill - i ballooned up to 200lbs - not an exaggeration...
PCOS is usually related to insulin issues as well...her pancreas can either release too much or too little - believe it or not - it is NOT the same for each W.....
For me? i have a deep voice, large hands, big boobs (38DD) and all my weight is settling in my mid-section. My blood glucose levels are low...but your daughter is different.
DO NOT let up on the doctors. Ask for a referral to an endochronologist as well!!
GOOD LUCK!!
