PCOS?

Hi everyone,
​I have been experiencing an irregular period ever since coming off the pill a little over a year ago. I went to my obgyn and she hypothesized that I may have PCOS. I have no symptoms other than an irregular period. I am healthy and have a good BMI. She sent me for lab work and noted all these other more invasive tests that may have to occur. Needless to say I'm very distraught and find myself getting extremely discouraged. I was wondering if any of you have been in a similar situation and have any advice or successes to share. I partly think that I am stressing myself out and that this is a major factor in all of this. I am waiting to have day 3 lab work done.
​Thanks!
