i was going to say totally normal but when the pain levels interfere with your everyday tasks - it might not be. i suggest contacting your dr/ob for a check up just to make sure everything is ok.
I'm also ten weeks and get a sharp pain every once in a while it goes away fast however. I think if it is getting in the way of things you should probably talk to your doctor about it, mine tells me it is basically my uterus growing. Hope all is well.
