Bacne while pregnant

Ca

Is there ANYTHING I can do or take?? Since my first miscarriage last year I’ve had terrible acne on my back. It’s gotten worse since being pregnant. I’ve tried everything, spray toners, tea tree oil, face cleanser with salicylic acid, moisturizer, no moisturizer. I’m getting so frustrated it’s been a year of this.

(It only started after coming off birth control)
