Pregnancy cramps?

Haley • Due December 23, 2016 with baby # 1! 👶🏻
I'm almost 5 weeks and every day on and off I've had cramps that seriously feel like my period coming. It's to the point where I keep running to the bathroom expecting to see blood. They aren't extremely painful but it's enough to make me think it's my period when I know it's not. Anyone else have this?
