Using your phone, sign into iCloud and change your password. Remove all you’d devices, expect your phone. Don’t sign in anywhere else. Wait and monitor your account. If that works, then start running a scan on your PC. Because it’s likely you have malware on it. Your iPhone (unless you jailbroke it) is secure. It unlikely the hacker infiltrated iCloud or is doing anything other than copying the password you keep re entering on your PC.
