I just started my first pack of Microgestin 1/20 this month and i took my last pill today before 7 days of sugar pills. My period is 3 days late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>. I've heard that the sugar pills control your period so I wouldn't get a period untill I started the sugar pills? Is this true? Should I be worried? Please help
