Should I worry?

I was checking <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> today and it says I have a high risk of pregnancy today (7.4%) and I remember when I had sex (unprotected and no withdrawal) on the 19th it said 3% chance at first I was thinking that wasn’t that high but if 7% is high is 3% like medium? I’m trying not to worry until I miss my period to prevent it being late but I also don’t wanna be surprised 🙃🙃 what do y’all think?
