Anyone with the patch or has an experience with the patch?

CHINONYE

So I got on the patch about and this is the third week so far, my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> says that I'm supposed to start my period in 2 days. I don't know if I'm supposed to have a period yet or not. Does anyone know what to do because I really am confused and panicky? Am I supposed to be on my period this early or is that supposed to be on the 4th week?
