should I even bother?

Hi.. I am so new to this app and never thought I'd need it until I decided that cool, maybe it's time to start a family. Long story short, I've followed the app because to be honest before the this app I wasn't sure when I was ovulating and so on. Anyway, I was meant to start my period today (if things did not go as planned). But, what I thought was implantation spotting ended up being a full on period. I have a pregnancy test, but not sure if it's worth checking... what do you ladies recommend? Have any of you had your period and still ended up pregnant?
