Drug knowledge symptoms and conditions

i absolutely hate this pill. i have only been on it for a couple of days and i feel like im going to die! my breasts are not tender but i constantly have headaches, diarrhea and vomit all the time. I hate it but then again im not gonna say its the worst pill bc its the first time i am on birth control. i don't know if i should keep taking it or just stop. also, im a little confused on how to take the pill bc my doctor just handed it to me without telling me ANYTHING about it even when i told him i have never been on any kind of pill before. he was dumb. if anyone can please explain to me how to take them i would really appreciate it. i am just nervous that my period wont come once i get to the brown pill and what if i take all the brown pills and it doesn't come? what do i do? start a new pack? im sorry if i sound dumb but my doctor shouldve told me everything about this pill before he prescribed it to me.
