I have PCOS too and it never showed up in my bloodwork until I got quite sick.
Heavy periods, adult acne, weight around middle (tummy fat), cravings for sugar/carbs, hair where it doesn't belong (I had a few on my nipples, my Mom said everyone does... actually, not true lol!), early onset of menses, heavy and long periods, ie. longer than 5 days.
So I have had it my whole life, and I had no idea until I was rottenly ill.
I would look it up if I were you. You can somewhat control it with diet and exercise. I am on Metformin now for it.
