Hi, Arlene,
This seems like a sign of a dermatological condition, do not panic, just breath deeply, and try to see a dermatologist, if the issue persists after any medication they prescribe, then you should go to a family doctor, or specialist for deeper examinations.
Take care of yourself and your baby.
Good luck.
I am very worried, I don't know what it could be, I have a ultrasound on Wednesday but I would like to have some kind of confirmation that my baby and I are okay.
