When to Start Taking the Birth Control Pill?

The birth control pill is a hormonal medication taken daily to prevent pregnancy. It contains synthetic versions of the natural hormones estrogen and progesterone. There are two types of the birth control pill: combined oral contraceptive pill (COCP) and progestin-only pill (POP).
The POP only contains progestin as opposed to COCP's combination of estrogen and progestin (synthetic form of progesterone). This is because some women cannot take estrogen due to medical reasons and are recommended the progestin-only pill. COCPs are the most commonly used pill worldwide, and hence, this blog primarily focuses on them.
There are three common ways to start the birth control pill. The right choice depends on your cycle, personal preference, and whether you need immediate protection.
First-Day Start
Take your first pill on the first day of your period.
If started in the first five days of the period or the menstrual cycle, combination pills become effective immediately. so you don’t need backup contraception (like condoms) when having sex.
It helps with cycle tracking, as the pack will align with your natural period schedule.
Sunday Start
Take the first pill on the first Sunday after your period begins.
If your period starts on a Sunday, take the pill that same day.
This method was designed to keep menstrual cycles predictable, ensuring that most periods happen on weekdays rather than weekends.
Use the backup contraception for the first 7 days, as the pill takes 7 days to be effective.
Quick Start
Start the pill on any day of your cycle, even if your period hasn’t started yet.
This method is often recommended if you do not wish to wait for your next period before starting birth control.
However, protection is not immediate - if you start the pill more than 5 days after your period has already started, use backup contraception (like condoms) for at least 7 days.
Effectiveness Based on Start Time
Start Method | Immediate Protection? | Backup Needed? |
First-Day Start | Yes | No |
Sunday Start | No | Yes (7 days) |
Quick Start | No | Yes (7 days) |
Each start method is safe and effective, but choosing the right one depends on your needs. If you’re unsure, talking to a doctor can help you decide the best way to start.

24-Day Pack: Take one pill daily for 24 days, then take a pill-free break or the inactive pills (if your pack has any) for four days before starting a new pack. You’ll likely have a withdrawal bleeding during these days..
Extended-Cycle or Continuous-Use Pills: Some pill packs allow you to take active pills continuously for months, delaying or even stopping periods. This option is helpful for those with heavy, painful, or irregular periods.
