If you’re not already taking the pill or using another form of hormonal contraception, you can start taking the progestin-only pill at any point during your cycle. Or you can wait until you have your period.
When you’re ready to start using progestin-only birth control, pick a convenient time to take it because you’ll have to take it at this time every day.
If you start the mini pill on the first day of your period, you’ll be protected from becoming pregnant right away. So you don’t need to worry about using condoms until your protection kicks in.
You won’t be protected against pregnancy right away if you start taking it at any other point during your cycle. In that case, use a back-up birth control like condoms for the first 48 hours.
