So I've just recently started birth control (the pill) for the first time on Jan. 1st. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, my period is late by 3 days and I don't have any symptoms that it's near (I usually get a specific type of cramp days before my period actually starts). I still have about 4 white pills until I start taking the sugar pills. Is this just the process of my period regulating??
