There are three different ways to start taking birth control pills. First Day of Period Start: Start your pills on the first day of your period. Continue to take one pill every day at the same time. With this method, you do not need to use a backup method as the pills are effective in preventing pregnancy right away.
Can you start birth control in the middle of the month?
First, look at what type of pill it is. If you take your first pill within five days of your period, you're protected immediately. However, if you want to start sooner and your period isn't for a few weeks, you can still begin taking your birth control pills, but you won't be protected right away.
How long after you start taking the pill does it become effective?
It depends on when you start taking them. You can take your first birth control pill any day of the month, but you may need a backup birth control method (like condoms) for the first 7 days. If you start combination pills within 5 days after your period starts, you'll be protected from pregnancy right away.
