Some type of rash?

Dakota

Hey everyone.. I haven’t posted in this group yet, but I’m almost 33 weeks (due the 27th) and I’ve been having Braxton Hicks for 3 hours, I’ve been super nauseous. I decided to take a bath, and as I was getting naked, I saw this on my shoulder blade. I didn’t have it last night when I went to bed.. is this something I should be concerned about? Like it appears and I feel so sick. Please help..
