Throbbing sensation

I'm 14 wks today and I'm not too terribly worried but I'm getting a throbbing sensation in my uterus...(too low to be my abdomen) my pap came back good so I'm not too worried about all that, I'm just curious if anyone else has this...it's happening as I type this...it's off beat so I don't think it's my heart beat, it's too slow. Could it be baby kicking?? Any thoughts or comments would be greatly appreciated!!! ?
