I have red bumps that itch terribly in different areas. I suspected flea bites, but could it be pup? I am 37 weeks pregnant. Could it be pup?

Itchy bumps. Itchy bumps can be puppp (pruritic urticarial papules and plaques of pregnancy) are one cause of itchy bumps. Flea bites, contact dermatitis, eczema, scabies and other causes are among other possibilities. I recommend you see a board certified dermatologist for help with this. Good luck.
