Okay so I did a test on what happened and found why it did not alarm this morning. So aside from setting the alarm feature to wake me up at 830am I also put an alarm on my calendar to "alert me" 30 before 9am. So tested it just now and the alert on the calendar vibrated, which then does not set the Alarm off after the alert from the calendar.
I knew I did not sleep in cause any small sounds usually wakes me up and this is the first time an alarm did not wake me. I tested it cause I was going to use the alarm feature as my primary alarm when school starts back up.
In summary:
Do not set calendar and alarm to alert you at the same time. 
that was why last week it worked and not this morning
