hi guys. im new here and i need help. I have moderate acne and have tried doxy+ duac with no results ( tried for 8 months-made it worst)

Im good at treating my acne with skincare, however i have not managed to control it.

I have no dairy, which helped a little. I also have limited my gluten but i dont think my acne is caused by diet. I am clear for 2 weeks then i breakout when i start ovulating. This leads me to believe my acne is hormone related, well actually im 99.9% sure its hormone related. i am 20 years old and i only got acne a year ago. I do not want to take any oral medication because i have medical problems. is there natural methods or other vitamins that help with hormonal acne? i am taking no vitamins.
