Dermatology question

Mrs. R
I am 6 weeks pregnant, almost 28 years old and have had severe acne for over a year. I have suffered from breakout after breakout my whole life though, this last year just has been the worst. I made a dermatologist appointment before I became pregnant. He said he can't do much but did give me 2 topicals. Finacea & Clindamycin. Has anyone else used these and also used while pregnant? They said it's safe and schedule b class. Thanks in advance!
