Lower back pain

First time mom here and I’m absolutely terrified of having a miscarriage. I believe I’m about 6-7 weeks pregnant but my first doctors appointment is March 15th... that seems like forever away😞

I’ve been having pretty bad lower back pain and I saw that this could be a sign of a miscarriage (I probably should stay away from google😔).. does anyone know if lower back pain is normal ??

My boyfriend keeps telling me I can’t stress and I’m trying so hard not to, I just feel so anxious about having a miscarriage. I think about it everyday and I even had a dream about it a couple nights ago. How do you keep from stressing about miscarriage during pregnancy??🥺💔
