late on my period

Guys <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> is saying I am 4 days late on my period. Last month I got it on the 10th and had sex on the 14th. Haven't gotten my period yet and Last month was my first month using <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> so it's the first month I have tracked so I don't even know if I'm irregular or not someone help! 😭
