Abortion , Accutane and Implanon

Patient: I got an abortion on 2nd April -4th Aprril I was given pills of a set of 5 to put under my tounge – 1 on 2nd and 4 on the 4th . I got an Implanon on my left hand on the 14th . I am considering to take Acutane (3times a day ) for 6 months – Will taking accutane make Implanon less effective and what are the side effects ?
