Pregnancy Chance? (Am I Being Stupid?)

So I’ll be 17 in a month and I’ve been w my bf for almost 2 years. Him and I started having sex like 8-9 months ago. I’m on the pill and we USED to use condoms but then one day we decided we’d try it raw “one time.” Ever since then for many months now we don’t use condoms. I take my pill on time and have never been late once and he pulls out (yes I know not a form of birth control but I’m just saying) I just wanna know if I’m protecting myself from pregnancy enough? (Him and I don’t have STDs btw) whats your experience with the pill?
