Sex with Nexplanon after 9 days of insertion

So, I had the implant Nexplanon inserted 9 days ago. I was informed to not have sex for 7 days. I had unprotected sex on day 9 after the insertion and my partner came inside of me. Is there a chance I got pregnant? Or am I just being really paranoid? It's my first time getting the implant so I'm over thinking everything I do on it haha
