is it possible to get pregnant on birth control?

hiiii. so I started birth control pills like 3 months ago and I’ve been taking them every single day like I’m supposed to. of course, there have been several days when I forget to take them one night but I always just take that one the following morning.

My boyfriend and I always have a condom on when we have sex either way.

I’ve been experiencing some tender breasts the past few days, and my belly is really bloated. But it’s my fertile week and today is the last day. I’m having normal discharge I think, it’s clear and sometimes white. Idk, is there a possibility at all?

Thanks :)
