ok i went to my PCP in October (?) to figure out what the cause of my weight issues were.... or why..... i had gained nearly 100lbs in a single YEAR

it was absolutely horrible i had had acne since fourth grade dandruff that you would not believe and just oily skin in general..... my hair fizzed unbelievably A( for those who dont know i have found articles that related the 2) i started my period on May 23, 2006 ( i had band concert that day ) it has been pretty regular skipped a month here and there i cramp very bad and also its heavy. i seem to have thinning hair although it is so frizzy that it dose not matter.
( although im very blonde like almost bleached i can see hair all over my arms a mustache ( all really ligh tbut still there!!! also on the tops of my hands and knuckles and and i have hair like a strip from my belly button down ( black) ... TMI srry)
ok so i went to my PCP and he ordered blood test to test for diabetes and hypothyroidism ( SP?) the results came back neg. but i had an unbalance in my cholesterol.... low good normal bad during the initial visit he asked if i have ever heard of PCOS..... i told him yes because i had and then when i went to the follow up he said he had put a referral to the endocrinologist in before the tests came back ( or thats what he made it sound like to me ) i have not seen the endo yet but the insurance company is NEARLY there just waiting on an appointment!!!
so im asking is there a chance that i have PCOS???? ( i also have a skin tag which is very small in between my breasts)
srry it soooo long thanks in advance any replies are appriciated !!!!!!!
