Bad cramps

Lee
Hi guys :) I'm 8 weeks and 1 day pregnant. I went to the hospital with bad cramps the other night and everything seemed fine. It shopped for a few days but now I'm cramping again and I'm so exhausted! I don't have energy in work and I am doubled over in pain so much. Not sure what to do :/ I've had a miscarriages before but it never felt like this. Any advice?
