Rash 13w+5d pregnant!

Hello! Is this normal to get rashes when pregnant? It's like small red/brown dots all over my boobs & chest mainly. Also it's started to go down my arms & on my belly 🤔 the dots are a bit darker than shown on photo, can be itchy a little on my chest & breast sometimes. Probably just another symptom but if any of you could shed a little light. Thanks in advance guys!! 🙂
