small itchy red bumps/patches on boob

Gracie • mommy to be❤️april26

I'm 11 weeks pregnant and the past 2 or 3 weeks i've been getting these tiny brown/red spots on my boobs. i get them on my cleavage, under boob, on boob, and shoulders. i read that it's normal to get pimples and stuff on ur boobs but nothing says anything about it being itchy. what could it be?!?!! and what can make them go away??😩
