I started itching all over my body, the inside of my arms, neck, stomach, back and breast. I did some research to see what rash I have and found something similar to my itching and the way it looks. I found a pregnancy rash called PUPPS rash that looks similar to mine. I read about it and it is said to be common in first time pregnancys, but I m not sure if I m pregnant. I m 18 years old, not allergic to anything, sexually active, no medical history. Could I possibly be pregnant and not know it and have this rash?
