Paranoid

I had my nexplanon put in my arm on April 5th around 1pm , Today is april 12 I was told to wait 7 days before its effective , Me and my bf had sex today around 6pm and I never let had anyone cum in me before except him. Idk if My birth control is effective or if I had to wait 7days after :-( or if the 7th day was ok. im super paranoid honestly, I went pee right after he came in me too
