Curious about pregnancy rash

I haven’t got a clear positive but my intuition is strong and I keep getting extremely faint lines. Yesterday I got this rash it started on my neck and has spread to my chest, arms, ankles, and jaw. When I looked up rashes it said it’s common to have a rash during the two week wait. Has anyone ever had this then ended up being pregnant?

I’ve never had poison ivy. I’ve walked through it, I’ve picked it unknowingly, I’ve had my son get it and rub all over me and still never got it. My skin is not super sensitive. I’ve never had a reaction to any medications, foods, soaps, detergents, poisons plants. I have only ever gotten heat rash, fever rash, and some funk that my brother got during football and spread through the whole house.
