Nervous reck! 2 Days late

I've been posting but not many answers, can't sleep right now. My question is can you get pregnant 5 days before your next cycle? If your has ejaculated inside of you? I had sex on the 10th & 13th PROTECTED With condom on the 20th I had sex UNPROTECTED & remember feeling the ejaculation inside, got up to go the bathroom right after but I been reading & I keep reading "you can't get pregnant on the days you aren't ovulating. I don't recall with my last pregnancy how it happened. It been over 4 years. Update the test read NEGATIVE which means that I didn't get pregnant during my ovulation days or my period is late.
