Please help? Pcos?

Ash. ttc baby #1 with pcos

Hey so for the past few months i finally decided to ask the doctors for help. I had a blood test and at the time that month it showed I wasn't ovulating that month. I've got another one booked to see if I'm ovulating again in just over a week if not they are going to refer to a fertility specialist, but will they even help because I'm over weight? I'm about 18 stone :( . I've been having unprotected sex with my partner for 5 years with no bfp at all :( now I'm thinking I have pcos, I have unwanted body hair on my back, bum and face and on my stomach, I do have periods but sometimes I can go a couple of months without having one. I went through a stage of having them pretty much spot on for a year or so, I have just had a period after not having one for about 3 months. Does anybody else have this and was it pcos? I am overweight and I know there just going to say to loose weight but I find it so so hard. Thank you for anybody that replies:)
