I switched to a higher dose of birth control right after the 7 placebo days in my old birth control pack; did I have to wait 7 days for the new pill to be effective?

Great question!

If you are sure your new birth control pill is a higher dose, and you haven’t missed a pill, you don’t need to use a backup.

Remember, If you are taking your birth control pills correctly, consistently and all of time you are protected from pregnancy by 99% for the entire month.

If your new pack was a lower dose, you would need to use backup like abstinence or a barrier method like condoms for a week. This is because when switching to a lower dose, it would take your body 7 days to adjust to the new hormones, and you may not be protected during that 7 days.


It’s also important to remember that hormonal birth control methods do not protect you from STIs. Use dental dams and condoms during oral, anal, and vaginal sex to help reduce your risk of STI transmission!
