Help!! Sharp pain.. What would you do??

Victoria
Ok ladies I went to stand up with my daughter and got a real sharp shooting pain down the side of my stomach.. It also happened a couple nights ago when I turned a certain way in bed..(it has happened in the past when I was not pregnant) it lasts for a few seconds and then goes away but this time I now have very light cramp like pains in my lower abdomen.. Would you go immediately to get checked or just wait it out alittle??
I'm 5 weeks pregnant
