Birth Control Pill

How do birth control pills prevent pregnancy?

The birth control pill works by stopping sperm from joining with an egg. When sperm joins with an egg it’s called fertilization.

The hormones in the pill safely stop ovulation. No ovulation means there’s no egg for sperm to fertilize, so pregnancy can’t happen.

The pill’s hormones also thicken the mucus on the cervix. This thicker cervical mucus blocks sperm so it can’t swim to an egg — kind of like a sticky security guard.

How do I make the pill work best for me?

Forgetting pills, losing the pack, not refilling your prescription on time — these are the main reasons why people might get pregnant when they use the pill. It’s good to plan ahead and think about the best way for you to use the pill correctly. Here are some ways to help you remember to take your pills every day:

• Use our birth control reminder app or set an alarm on your phone.

• Keep your pill pack next to something you use every day (like your toothbrush or phone charger).

• Keep your pills in your bag so they’re always with you.

• Be pill buddies with friends or family members who also take medicine every day, and help each other remember.

• Your partner can help remind you.

Do whatever works to help you take your pill on time, all the time. Depending on where you live, you may be able to order and refill your pills online through the Planned Parenthood Direct app.

Want to be super duper sure you don’t accidentally get pregnant? You can also use a condom every time you have penis-in-vagina sex. That way you’ll be protected from STDs too.

Does the pill protect against STDs?

Nope. The pill is really good at preventing pregnancy, but it won’t protect you from sexually transmitted infections.

Luckily, using condoms every time you have sex really lowers your chances of getting or spreading STDs. Condoms also protect against pregnancy — so using condoms + birth control pills together gives protection from STDs AND awesome pregnancy-preventing power.
