I took a test!

I took a pregnancy test on Saturday morning it was the dollar tree test just to see! I had already been 9 days late but it came out negative! But my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app is saying that I'm 12 days late and I'm 27% pregnant! I don't know what to do now! So if someone have some advice could u be kind enough to share with me!Thanks!
