Acne help!!!!

I'm about 6w pregnant and my acne is already flaring up! I've always struggled with hormonal acne, sometimes cystic and very painful. I've just started breaking out all over my chin/jaw line and it's very painful! I can't deal with this for 9 months. I'm afraid to use my normal cream and treatments bc of ingredients. How are you treating your pregnancy acne? What has your doc recommended? What products should I use?! Help!!
