Has anyone got pregnant on birth control?

I’m almost 6 months pregnant and after I want to take the pills to prevent pregnancy right away . I know after having a baby you’re extremely fertile to have another. I only like the pills and been seeing a lot of post of females getting pregnant on it. If you take it everyday same time and on top of it, CAN you really get pregnant? Anyone have it happen? I’m sure the ones saying they got pregnant are missing hours or even a day of the pill. Thanks in advance!
