Cramping/Braxton hicks?

Sirena
I'm 11 weeks 2 days, first pregnancy, have been having some cramping that's not severe, but uncomfortable especially when I sit a specific way in a chair or the car driving. Laying down I'm not bothered by it unless I need to use the bathroom. I thought at first it was the need to poop but I'm fine in that department. It comes and goes and isn't there for more than 20 minutes. Just wanting to know if anyone this early has ever been through this.
