I had sex exactly 5 days after having the Nexplanon put in. what are the chances of me getting pregnant since I didn't wait for the full 7 days, I'm already a week late on my period

It is possible since the week is to allow for the drugs to take action. If you are more then two weeks late then take a home pregnancy test.

One of the side effects is irregular periods. You could also be experiencing this.
