Braxton hicks?

Brit
I'm 39+4 and this morning at 0311 I started having cramps that woke me up. I timed them and they came for about 45-60 seconds every 10 minutes. This lasted about 2.5 hours then I was finally able to fall asleep and they went away! I thought for sure I was in early labor but I guess they were Braxton hicks? Does anyone have any experience with this?
