Itchy skin, 16 days PP

I have itchy skin. I’m 16 days pp and the itchiness is random. It’s like all over my arms and legs I feel itchy. What can I do to help it?

I’m using hydrocortisone every other day because it’s not good to use it daily for a lengthy time. I’m using cetapil body wash and lotion.

Not sure what else to do but sometimes the itchiness keeps me awake at night.
