Am I pregnant

I've been on Nexplanon for two months and I waited a month to have sex with my boyfriend. We used a condom the first time but after that we didn't but he still pulled out. When I got the bc I started spotting a week later and it lasted for a month and a half but it recently stopped. Other than the spotting ending I don't really have other "symptoms" think I'm just being paranoid about it like I am with everything.
