New Years mistake? HELP😣

So the night of New Years I had unprotected sex. We were having a good time and then he put it in and then it finally kicked in it was unprotected. It was only for a minute or two max and he didn't cum. Should I get EC? It's been 2 days and now I'm starting to get stressed from people saying I can " still " get pregnant 
Also looking back on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> I was "fertile" at the timeÂ
