second guessing myself

i have been on junel fe for about 6 months now. 3 weeks ago me and my boyfriend fucked raw, then last week we did it raw again 3 days in a row.

i take my birth control very promptly, but now i’m always tired all the time (could also be because i’m back in college) and im eating a lot more (possibly from smoking so much) but still i find myself thinking the worst.

i know there’s a chance of me being pregnant because of how often i have gone raw, yet he has never finished in me (only once he pulled out a second too late). how effective is my birth control in protecting me if i use it perfectly?
