switching from pills to nexplanon

on january 23rd i got the implant Nexplanon put in because i was tired of remembering to take the pills everyday. the doc said take the pills a week after they put it in for no gaps. & i did. the thing is 8 days after the implant was inserted, my boyfriend finished in me thinking it was okay cause it was a week. but i’m not forsure if it is okay. could someone help i’m kinda freaking out. lol. :( i’m currently on my period right now
