Eve keeps telling me I'm 7 days late, it's getting to me

So I started the pill two Saturdays ago (the 20th). My doctor did tell me I could wait until my period started on the Wednesday but it may be easier this way as I wouldn't get so confused with the pack due to it being in order. Because of this hormones kicked in before my period was due last Wednesday causing me not to get it. Like I'm 7 days late I know, I expected it but everytime I go on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> it's staring at me that I'm late and now it's starting to stress me out. I know it's a mind thing but anyone know how to change when my period is expected on this app so I can put it to when I start my sugar pills?
