Any suggestions on how to tell my boyfriend?

OK, so my boyfriend knows there's a chance that I might be pregnant. The thing is, I've been taking HPTs and the faint line keeps getting darker, so I'm pregnant. How do I tell him that I am? And we weren't TTC, I just must've ovulated late and we weren't as careful as we should've been around then. I want to do it in person and might see him tomorrow and/or Saturday.
