I am 19 and this is my first month on birth control. I began my first active pill on feb 21, the first day of my period. It is just 3 weeks later now (3/14) and im starting my inactive pills so does that mean i'll be getting my period early? Also am i still protected if i have intercourse while on an inactive pill if it does end early? If i don't get my period this week, and i get it next week, should i take the active pills while on my period?
