Need advice urgently

Rebecca
I had a whole heap of tests done last week plus ultrasounds and I found out that I have hypothyroidism which is making it hard for me to concieve.
I went to see a dietian today and seen my doctor after it and he did me a referral for sleep study and on the referral he put pcos as medical history but he didn't put it on any of my other referrals. 
My question is, is it possible to have PCOS if I have regular cycles and ovulate on time?
