Does Taking Krimson 35 To Postpone Periods Affect Chances Of Conceiving?

Hi, i am going to get married in another 2 months. I expect my first day of my menstrual cycle on the wedding date. I would like to postpone my periods for 2 days. When i consulted a Gyn Dr, she prescribed to take Krimson 35 for 3 months. I fear whether it will affect the chances of getting conceived (we have planned for the baby after an year). Kindly advise on the same.
