Left side stitch/cramp

I’m 6 wks 3 days. First pregnancy. I’m experiencing a dull but constant stitch in my abdomen on my left side. Every once in a while the feeling will intensify but goes back to dull within seconds. I can feel it a lot when laying down or walking.

No spotting. Nauseous but no vomiting so far. Getting nervous and don’t know if I’m over thinking it.
