New iPhone se alarm going off but none set

Hi there

Got a new iPhone se a few days ago and the alarm keeps going off at 7am but there are no alarms set. Today I don’t even have the option to stop it. It’s just snoozing and then going off again and again. All I can put it down to is that when I set it up Friday it backed up from my old iPhones Thursday back up which had an alarm set for 7am Friday. I’ve deleted all alarms, no bedtime set, no third party apps. Please please help
