My boyfriend & I had sex during my fertile window & my period is 7 days late. I'm freaking out because <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> says there is a 7% chance of pregnancy, but the test came back negative. We don't use protection (we opt for the "pull-out method") so if I am it's not a problem, I'm just confused.

I'm 22 b.t.w
