I am 7 months pregnant and I started forming rashes all over my legs. I think it's Pupp. It's really itchy. What can I do to alleviate the itch

To ease the itch, try taking an oatmeal bath or add baking soda into your bath. Keeping your skin moisturized could also help reduce the itchiness. You can consult your doctor for medications that are safe for you to use. Hang in there...
