EWG confusion/panic about products in pregnancy

I’m 25 weeks pregnant and recently realized one of the daily products I was using on my face was a 6/10 on EWG. I legit lost so much sleep about this and spiraled. My OBGYN calmed me down as well as people in my mom’s group. However I looked into other products we use that I assumed were healthy based on the fact that they are all the things “free” (no phthalates, parabens, fragrance, etc.) . Well I was surprised to see on EWG some of these rated a D- while Clorox products are an A? I know some people find EWG controversial and I am curious if you know why they allow perfum (fragrance) in some products and not others & then rate certain obviously chemically laden products like Clorox and A? What is the deal here
