Does this look like an OB?

I have had gen herpes for years but never anywhere else. After recently having a uti and being on macrobid and briefly on bactrim I thought I had a rash due to a sulfa allergy. So worried I may have had an OB and given to my son.

One dr said it didn’t look like an OB and another said it did. Day 3 vs day 10. I have a few other random spots on my arms that look similar to bug bites, off on their own not in clusters

-wouldn’t take the day 3 photo for some reason 🤦🏻‍♀️
