Notifications iPhone 13 Pro & Apple Watch SE

Ever since I started wearing an Apple Watch I’ve had three versions now, I’ve had nothing but problems trying to get proper notifications between my phone and my watch. Now with the newest watch I am wearing it at night to try and get the sleep app information. And the alarm that is always gone off every morning at 5 AM is no longer going off on my phone and once in a while it goes off on my watch but not my phone. Does anyone have any suggestions how to fix notifications? Also I don’t get text message notifications on my phone if I’m wearing my watch either
