Benzoyl Peroxide during pregnancy?

I've read a lot of conflicting things about it and I'm so confused. I just went to the store earlier and bought acnefree face wash which has only 2.5% benzoyl peroxide but now I'm unsure about using it. I just need a solution for this acne! I've never broken out like this and I'm only 9 weeks lol. But anyways have you ever or do you use products with benzoyl peroxide? Did your doctor approve?
