Pain while pregnant

Gerycah

So I went to the doctor last night with a sharp pain in my lower belly and aching pain in my back. Dr did a ultrasound, he couldn't see the baby but I am only 5 weeks 2 days. They did a beta HCG blood test on me. And my levels are at 1037 mIU. He says they are fine but just got to go back and retested in 2 days. My pain is continuously getting worse so back to the dr I go. Has anyone else had this but continue on to a healthy pregnancy?
