Pain??

Okay ladies.. im 13 weeks and some days so I know baby is only like an ounce.. but is it possible that she/he is sitting on a nerve already because in my right knee and right elbow, I have a good amount of pain. Not horrible, but its pretty constant for a few days now and I wasn't in any accident or did anything different..
