7th day of nexplanon.

I got my implant on Wednesday the 3rd and my doctor told me to wait 7 days to have unprotected sex. It’s not Wednesday the 10th and it has been exactly one week, or 7 days. My boyfriend and I had unprotected sex and he finished in me twice. Not super confident about the 7 days thing. Should I be concerned or am I freaking out for no reason?
