help! how to get rid of an itch

🤰💙
I started itching really badly last night - my breaths and belly and I'm going crazy and I look funny trying to avoid scratching myself., I get to see my Obgyn in 2 days and I can't wait for him to recommend something ...  WHAT DO YOU GUYS RECOMMEND FOR ME TO USE THAT WILL HELP ASAP?? I heard lotion with oatmeal should help or some kind of oils...
