so basically I've been on birth control for 2 months now and I'm pretty good at taking the pill but sometimes i slip up and forget to take one but i always take it as soon as i remember. so recently i have missed pills but i can't remember if i only missed one or two..... another thing along with the missed pills is that i used to have cancer and had chemo for 9 months which greatly reduces my chance at fertility. right now i am very nervous i am pregnant but i know it's a slim chance. i am only 17
