Possibility of Pregnancy?

So, my SO and I had sex & he accidentally did not pull out, but i am on birth control. on this particular day, i had forgotten it that morning (rare for me). Because I was only about 5-6 days away from my next period start date, i wouldn’t exactly be ovulating. to be exact, one of the websites i looked at indicated 5% chance that i was that day.

i just took a digital test and it indicated not pregnant, however, this was saturday the 2nd that it all happened. i know it’s way to early to test, but i’m anxious. if i am, we’d both be so excited, but no it was not planned. any thoughts on the possibility given the facts? i just need to talk it out 😂
