i’m a beginner please help

okay so i got my 21 pills yesterday i started my period yesterday so my aunt says i should wait till i’m done with my period then start taking them everyday at the same time right.

so my questions are when should i actually take my pills? (she said she assumed to take them after my period)

also should i take them in the morning?

any tips?

anddd.. do you not take the pill while on your period or?? cuz i only have 21 pills

this is my first time and i’m scared to take them i am sexually active so i thought it’s better to be safe er just in case. i’m 17.

please and thank you!!<3
