How do I log that I'm on the pill?

Chloe
I really like this app and before I went on the pill it was always so correct about when I would be on my period, but now I'm on the combined pill so I want it to record when my period will be with it and yes I know that I take the 21 pills and I'm on for 7 days but I want <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> to be in sync with me because this is such a great app!!!
