Aiyoo first time mom things can be scary kan! Those red spots could be heat rash, PUPPP rash, or even part of the stretching process, honestly best to check with your gynae or doctor just to be sure, especially since it's itchy, because some pregnancy rashes need specific care. A few of us had similar red patches during pregnancy and turned out to be nothing serious, but getting it checked gives you peace of mind and they can recommend the right cream for the itch!
