Red patches on lower leg... 36+5 weeks

Kristen • Momma to 3 beautiful girls (2 of which are identical twins). Trying for final pregnancy (hopefully a boy!)
Anyone else get red patchy skin, almost looks like a rash? It's not hot to the touch and it's not itchy at all... been there for a couple weeks. I've got a patch on my left shin and a patch on my right calf... just weird. Forgot to ask my OB about it on Tuesday... defiantly will next week though.
