Should I go to a ER?

Megan
So.. This is my first pregnancy, an I'm very worried. For about a week and half. I had sharp painful cramps, about four days ago. They were only to my left side, and lower belly. They seem to have lessen today but come up once in awhile.. I am close to five weeks now.. an I'm very worried, sure I tell my fiance to take me to the ER.???
