Period coming without warning

🖤💋💀💋🖤 • Just here to keep control of my AF :)
You know how most females usually feel symptoms before starting their period... Is it normal not to have any at all? I'm just wondering because I started without warning usually my breasts get super tender but this time nothing at all!! I haven't been sleeping well lately and been stressing could that be the cause? Please let me know thanks ladies :)
