Stomach cramps?

Jackie
I'm 18 weeks and 3 days today but for over a week I've had the worst lower pains. Like bellow me waist band and it's an extremely sharp pain. Sometimes only on the left side then it'll move to the right. Does anyone else have this issue or no any solutions. Would hate to go er and look dumb if this is normal lol but damn who knew pregnancy could be this painful already..
