Is it too late?!?!?

So i know having unprotected sex isn’t good when your not trying to have kids, but help! I had my plan b Ella the one for 5 days after unprotected sex, but I had some really stressful &’ scary family issues I had to attend for almost the whole week, now that I’m home day 6 after unprotected sex I remembered I never took it😒 can anyone advice me on what to do. I hate the fact that we have to take something so un natural to not get pregnant. WOULD IT BE TOO LATE TO TAKE EITHER WAY?!?!? The reason why I ask is because I don’t want to take something that will affect a existing pregnancy. Please no rude comments.
