What pregnancy glow?!

Sarah • First time expecting. Baby due 3/2/2016
Currently 12w  5d pregnant and I'm wondering where this stupid pregnancy glow is that everyone use to talk about when I was growing up? My skin is pimply and dry, my hair is dry and gross, I feel heavy and look tired all the time, it's awful.
All my friends looked completely normal and beautiful while pregnant. I have never felt so gross and I can't even be bothered to try to make myself some what decent because of how tired I feel. 
Am I the only one who doesn't have pregnancy glow?!
