Cramps in early pregnancy

br

Hello I was hoping someone could help me out with answering a couple questions. So I just found out that I'm pregnant. I am only 2-3 weeks along. And for the last 4 or 5 days I have been having these horrible cramps. Not light or mild they are sharp shooting pains. In the day time it's not that bad maybe a cramp or two (still painfull) but when I go to sleep it gets 10× worse. I wake up like 4 or 5 times a night from the pain and have to get up and move around until it stops. It's like a burning sensation almost. I know some cramping is normal but I'm wondering if I need to go in to the doctor for this.

Thank you so much for any input.
