Pain...

Yesterday I was walking and had a sharp pain in my right side of my pelvic area. Right where it's getting harder. It lasted a few hours and then got better. No bleeding. Now it's the same pain but in the middle! It's uncomfortable when I sit, but painful when I walk. I'll be 10 weeks tomorrow. My drs office won't schedule an ultrasound to check things out :( I'm sure it's nothing but I can't help but worry.. Anyone who else get these sharp pains? I've never had this, I've cramped a bit here and there but it doesn't last long like this...
