Suggestion/Diagnosis

I have pcos, my period was normal but i missed period last month . This has happened earlier so i thought it was not a problem. Now I got my period this month but late and bleeding is less. Also from few days I can hear some continuous ringing/beep in my right ear. And I can hear my heartbeat when I go to sleep and my ear is pressed my pillow. Also my heartbeat becomes suddenly fast and I feel very strong pulse in my nick,arms, thigh,fingers, back What is happening? Which Dr should I visit a gynecologist or ent specialist?
