Who do I ask ?

I don’t want to jump to conclusions but I think I might have PCOS. I have weird periods , weight gain , I have extreme thick hair growth in face , and on my body in areas that are more common on men. I’ve also been to the emergency in the past for for pain to find out I have cyst on my ovaries..but most important I have not been able to become pregnant and we’ve been trying for 3 years. I’m just wondering if anyone has been through this ? And who ask I about this my general doctor or would I have to go to a gynecologist?
