WTF is this?? TMI maybe?? Please please help⁉️⁉️⁉️⁉️⁉️

I’m 38 weeks and woke up a few days ago with this rash on my face! I didn’t really think anything of it at first but now it’s day three and it’s still here! I called my OB about it and she said she would call me back, that was a few hours ago.. please help me out.. it doesn’t look like herpes does it? I’ve never had a cold sore or anything and I obviously got an STD check at the beginning of pregnancy and everything came back negative so I am just really freaking out
