so I took plan b about 11 days ago and that was about 8 days before my next period was supposed to start. since i’m not on any type of birth control, my period isn’t necessarily consistent, but consistent enough for <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> to usually get the right start day. I know that plan b screws up your period schedule, but if you’re late, how late are most people? i’m technically 3 days late right now.
