Not Gaining Any XP in Halo 4?

Hey everyone, quick question, sorry if this is posted in the wrong section. I reached the xp cap Thursday night at around 10:30 pm. It is now 12:45 am on Friday. When do I start receiving xp again?

I am kind of mad because I played 2 matches at 12:07 am and realized I wasn’t gaining any xp…

Thanks for any info.
