Acne?

I got acne with my period before pregnancy but was getting better as I got older, now that I'm in the family way I may as well be 19 again because my acne is terrible! It only gets worse if I try to wear makeup, or use any of my pregnancy skin products, which I used to, but have stopped. I'm wondering if anyone else is having this problem and if there are any make-ups or skin products that you have used and would recommend?
