spooked

okay so me and my boyfriend of half a year have already done some minor things such as handjobs etcetera, and right now I feel like I'm ready to go the full way. I'm on the mini pill and we also plan to wear a condom but I'm still scared of getting pregnant?? is there still a chance I could??

- I also took my pill twenty minutes late yesterday but I took it on time today,, will this lessen the effectiveness or would it only be when I take it late by a couple of hours??
