birth control, late pill, plan b, help!

for context: i had sex a little over 2 weeks ago and he didn't pull out or use a condom, and i took my pill perfectly until the morning after. i took it about 3 hours late and checked my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> and saw i was predicated to be ovulating that day, so i got a plan b and took it about 14 hours later. i've been spotting since then and it's all been brown and like period blood? and i was just wondering if i have a high chance of being pregnant? i'm so sorry, but i'm in a very tough situation, i promise i'm educated on this but it's hard for me to understand what's even going on right now cuz i know that my family will look down on me if i am pregnant... please help! i am really in a tough spot and will take literally any advice.
