Could I have PCOS?

I have never had irregular periods, they’ve always been on time. The past two months, I have not had my period, but I’ve had the worst pms symptoms. My boobs hurt, my head hurts, my skin is breaking out, I have found one or two dark black hairs on my neck or chin, I’ve been cramping, I’ve had the worst craving for chocolate and steak randomly, I feel like I can’t even make it through a day without napping, even if I sleep a good amount at night, and I’m SO MOODY and emotional. I thought I was possibly pregnant, but I never got a positive test so that isn’t it. The more I look into it, I’m wondering if I maybe have PCOS? I have an appointment with my doctor but it isn’t until the 8th and I want to try to ease my mind a little until then
