Alarm rings once then goes silent

Okay so i’m not sure what is happening on my iphone but some time this february or march, my alarm has been acting up. There are days where my alarm will ring once then goes straight to silent without me pressing a button or hitting snooze. Other days, the alarm works perfectly fine. I’ve caught my alarm sounding off once then goes to silent, so I know i’m not going crazy. I made sure that I didn’t have any other alarm apps besides the IOS one. I did a soft reset before to reset all of my setting and still the same issue. This has been my biggest frustration for the past few months and I can’t seem to fix it and it’s making me late to work.
