Acne during pregnancy

I am super excited to be pregnant and dealing with some of the things like acne doesn't bother me as much but I don't want it to get worse. For the past 3 days I have found my chin breaking out bad. I have 3 big knots that hurt. I get one pimple here and there from time to time especially on my chin however they all showed up at once. Anyone have any remedies or advice to ease my complexion?
