back pain 8 weeks

Elizabeth

I'm currently 8 weeks and have lower back pain with some cramping. No spotting or bleeding I contacted the 24 hour nurse line and they suggested I go to the ER if it becomes unbearable or I start bleeding. I've had a previous miscarriage so any pain or twinge has me paranoid. Anyone out there experiencing lower back pain and cramps but has had a healthy pregnancy? Are my symptoms normal?
