Should Krimson 35 Be Taken During Menstruation?

Hi am 30 years old mother and mother of one kid. Recently I was diagnosed with mild pcod. Due to that I started getting cyst acne on my face. Doctor prescribed me to take krimson 35 for 2 months. So that the androgen level decreases and harmones will start working properly. My question is when to start taking the tablets. Do I bed to take it during my cycles or later
