Today on my due date im getting brown blood, now it could be nothing but it says in the internet it could be a sign of pcos. I also have irregular periods, for the last 6 month I've had cycles 36, 32, 29, 28, 31. Are they not irregular enough to be pcos? I've got a GP appointment on Friday and want to see if he'll do my bloods to see if I'm ovulating, can he check for pcos too?
