Itching stretch marks

Maleah
Is anyone else experiencing itchy stretch marks 7wks pp? Im 7wk pp and my stretch marks are itching again...it would itch off and on. It would get inflamed for 3-5 days and stop for a few days and start itching all over again....help please. 😢 
Right now I'm using bio oil, vitamin e oil and mederma...but when it itches I use hydrocortizone....
