Foot hurts

So these past two days I went on a 30min walk & is pretty sure it’s the sandals I was wearing hurt my foot but it’s hurting me I kinda don’t know how to describe it but if I put pressure on this specific part of feels like a shooting pain or as if something is being pulled :( I’m wondering if I should go to the er , it only hurts when I put my whole body weight while walking . -21weeks prego
