This is my first time taking birth control. My doctor prescribed me microgestin 1/20 today. It is the first day of my period but she instructed me to start taking the pill today. As I did. I am confused about there only being 21 pills in the pack. When is the "inactive" week that I do not take the pill, considering I have my period and I am taking it? I am confused because I heard that you don't take anything, or you take (sugar?) pills during your period. But I am not doing this because I started taking it the first day of my period, and there are no sugar pills in mine - just 21 pills.
