Sharp Pains!!:(

I'm 17 Weeks pregnant, And ever since this morning I've been having a really sharp pain on the right side of my belly like as high as my belly button but to the right of it.  I try to rub it out, and took a bath but nothing is helping at all. Has anyone experienced this? I just had an ultra sound on the 7th and everything was perfect! I had cramping with my son but nothing sharp like this:/
