pregnancy acne


hey guys! this is my third baby and I'm 11 weeks pregnant! Iv never had any problems with my skin, I have great skin but for about a month my skin around my mouth and nose is so sore, red, and irritated! it looks like a rash more than acne but does have tiny pimples on it like once a week! Iv found bag balm helps it but then my face looks so oily! does anyone else have this and what helps your skin? it hurts and stings all day if I don't have anything on it! HELP!!
