I'm just curious!

I've heard that there are certain times a woman can absolutely not get pregnant, can someone advise me on which days those would be for me? This is my cycle.

I am only asking out of curiosity, I do not want a child and have and always will continue to use condoms. I just had no idea that there were certain times of a woman's cycle where pregnancy wasn't possible. I just want to learn more about my body and how it works :) thanks!
