Back pain

Hi ladies, I’m currently trying to sleep but I have annoying back pain and I can’t get comfortable. It’s lower back pain that is also around my hips. I’m getting worried that it’s a sign of miscarriage? I’m 4 weeks, and I’m so nervous! I went to the hair salon today so I was sitting down in awkward positions for a while so I’m trying to think that’s what caused it too opposed to the other alternative, or just trying to think that it’s normal pregnancy pains.

Can anyone help, please??!! I’m so nervous I can’t go back to sleep 😩
