Should I be concerned?

JLiz

I carried a basket full of clothes out to my laundry room (it's outside) and then brought back in another basket and right as I sat it down I started to cramp a little. I came to bed and rested for about 30 mins then got in the shower. I just got out of the shower and laid down again because im still cramping and my lower back hurts (very lightly). The pain kind of feels like a stretched a sore muscle on my belly. I'm 9 weeks pregnant and I don't know how concerned I should be. I was going to get ready to go out with my hubby, but now he says we should just stay home if cramping doesnt go away.
