Acne Issues When TTC? What's worked?

Ashley
I've never had flawless skin but since my husband and I have been TTC, my breakouts have gotten significantly worse.  Probably not surprising but mostly in my jawline.
I've heard that prenatal vitamins can contribute to acne as they contain DHA. 
I've read about trying Lysine and/or Zinc but neither seems to be recommended while TTC or during pregnancy.
If you have encountered this, did you find anything that works? Anything recommended by an OBGYN or a Dermatologists?
