I have been doing some investigation into insulin resistance and slim women and have found the following article below. It is obviously very new research but as it is from the BMJ, it will be good evidence to take to a GP if necessary.

Even lean women with PCOS are insulin resistant
Balen and colleagues imply that insulin resistance and hyperinsulinaemia are not usually present in lean women with polycystic ovarian syndrome (PCOS) unlike in those who are obese.1 In fact, data show that lean women with the syndrome are usually also insulin resistant,2 3 and such data were crucial in establishing that insulin resistance and hyperinsulinaemia are fundamental, causal factors of the syndrome.4 5
