Likely or no?

Is it REALISTIC to be scared of being pregnant if you’re on a combo pill and take it perfectly, use condoms, and your partner pulls out still with the condominium on before he finishes? My friend and I are both kind of in a panic about it. Maybe its just because everyone around us is getting pregnant and announcing their pregnancies or something but like....the pill taken perfectly prevents you from ovulating right? So you can’t really get pregnant unless God REALLLYYY wants you to be and makes it happen despite all the precautions...?
