Could these pains be because of a pregnancy?

I may be 2 wks pregnant. Starting yesterday I began feeling sharp "zap" or "zing" like pains, coming in spurts and still have them today. They are on my right side and almost close to my right pelvic bone... I'm not sure if this could be my uterus and be because of a pregnancy. What do you think or what have your experiences been? I am planning on taking a HPT on friday...
