Skin changes

Alyssa
I keep hearing that some skin changes or itchiness are normal, but I usually hear about them being more around the stomach area. I typically have no allergies or skin issues, but woke up yesterday with a blotchy sort of rash near my eye and today it is all along the left side of my face. I already have my 20week appt the beginning of next week where I can show my doctor and when I called about it yesterday they didn't seem worried, but now that it's getting worse I'm getting more concerned. Has anyone had anything like this so far or think that it is urgent enough to try to take off work and go have it looked at sooner? If it's common I just don't want to overreact, but I am not sure what products I could even use to help or at least try to stop it from spreading more if there even are any. Thanks!
