Am I pregnant?

In January I missed my period. This has happened many times as I am very irregular. Exactly 2 weeks ago today I had unprotected sex with my boyfriend. He didn't ejaculate but I found out one or two days later that there is the tiniest chance you can get pregnant from pre-ejaculation fluid. 
<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says my period should've started 3 or 4 days ago however the app has never been right as I am very irregular. I have had absolutely 0 symptoms of pregnancy but I am still worried because I'm only 17 and of course if I actually am pregnant there would be a total of 2 people who could support me with getting an abortion and all that stuff, neither of them being family members.
