3- 4 days: to reach a steady level of hormones can take 3 - 4 days.
This is why starting with the first day of your cycle, with your very first pack of pills, is useful, enough time before ovulation to be working as a contraceptive.

Triphasil (ethinyl estradiol and levonorgestrel): If you mean the birth control pill, you want to use condoms during the first cycle, and as of the second pack you can expect full protection from getting pregnant.

Additionally, if you start at the beginning of the cycle with the first day of menses with you very first pack, then most recent evidence suggests that 7-10 days of condom use is enough, but you must not miss any pills as this will significantly increase your risk of pregnancy. Take a pill daily, without stopping. Then your contraception will be 98%
