If that makes since! It's like the color of a bruise purple. It doesn't hurt or itch, (honestly I prob wouldn't have even noticed it if I hadn't shaves a few days ago. Anyway, it wasn't there a few days ago. I see my doc next week anyways but I can't seem to stop googling and worrying like a freak!! Anyone have insight? Same thing? Im.20 weeks pregnant
