What aches are normal?! I’m slowly driving myself mad…

I’m slowly driving myself mad not knowing what aches are normal and what aches are not normal. I’m only 4weeks 6 days pregnant, but my anxiety is in overdrive. Since before I could test one of my early signs were lower back ache, the ache hasn’t changed but now I’m going mad thinking somethings wrong. The bit that’s worrying me is a pain in my right pelvis, i actually get this a lot when I’m not pregnant anyway, so it’s probably not related, but I’m so confused.

This is such a ramble but I just feel myself going from 0 to 100 and I don’t know what to think anymore!!
