I need help

alright ladies I just found out on Friday that I'm pregnant. but cannot use the medications the dermatologist prescribed me anymore (for acne) I'm so scared I'm going to start breaking out like crazy literally terrified I already have horrible hyperpigmentation and I am very acne prone without that medication I'm stressing so bad and today is the first day without it swear I already see a difference.. I cry at the thought of seeing my face get to what it used to be it has destroyed my self esteem my whole life. I know I'm a pretty girl but I cannot see past the acne. when I'm clear I am totally confident with my looks. any suggestions? what to use while pregnant? what worked for u?I'm scared to use anything I might just do water for a while until I can't stand the breakouts anymore. I know there coming.....
