Body itches 6m PP

I am going insane. My body is terribly itchy. Started the same time I got my period and subsided after a week or 2. Now this month it started up again a day before my period. Starts on thighs and arms. Then down my legs and chest. All over and with no rash or redness

It obvious it has to do with hormones but how can I fix this?! Anyone else going through the same thing?
