the pill and Depo

Meghan • Angel Butt

so i was on the depo shot for 2 years. And I went off depo on April 25, 2017. the whole time I was on depo I didn't have a period. Then a full year off of depo still no period, and no other birth control was used. I finally started the pill 2 weeks ago. my question is I thought you were supposed to have your period on the 4 week, the white pill. But I've started my period on the 2nd week.
