10 weeks, 2 days one-sided uterus cramping & pulling...normal?!

Kimberly
I am 10 weeks, 2 days today. For the past couple of days, the left side of my uterus has felt very tight/pulled and crampy. I know that a couple of weeks ago, this was normal. But now that I'm 10+ weeks, is his still normal? Over a week ago we did have a sonogram where we were able to see our baby and it looked like the baby was on the left side of my uterus. Is this what could be causing the continual one-sided cramping and pulling? And is this still normal at 10+ weeks? This is my first pregnancy so forgive me if I am worrying wayyyyy too much!! I just want everything to be okay :-).
