Soooo itchy! 😣

3 weeks pp and last week I started to have an itchy belly and noticed stretch marks that weren't there when I was pregnant! What gives?! The itching is INSANE sometimes. I often use a hairbrush to scratch it bc my fingers just don't do it good enough. Anti itch lotion and ice packs only help for a few minutes at a time. I don't want to take anything like benadryl that might cause supply issues. The stretch marks on the sides of my belly aren't itchy, and never were during pregnancy either. Anyone experience this? If so, when will it END??!!? 😟
