Anyone experience this?

Kasie • Hubby and I are 27. We have an amazing 4 year old boy and beautiful 5 month old twins.💜💙💜
I'm 5w1d accordin to Glow. I haven't been to the doc yet. Making an appt tomorrow. Anyways, I'm experiencing sharp pains that come and go in the lower right side of my back. Does anyone know what is causing this. Kinda weirding me out. Thank you in advance.
