Types of contraceptive pills

Combination Pills (COCs): have 2 hormones estrogen and progestin. These are the most common type of birth control
pills
Progestin-Only Pills: these pills only have 1 kind of hormone progestin and no estrogen

 

As long as you take 1 pill every day, you’ll be protected from pregnancy. You don’t have to take your combination pill at the exact same time every day. But taking it at the same time is a good idea because it helps keep you in the habit of remembering your pill. You can also use an alarm or calendar reminder to help you remember. Most combination pills  come in 28-day or 21-day packs

If you have 28-day packs .

Take 1 pill every day for 28 days in a row, and then start a new pack on day 29. The last pills in 28-day packs of combination pills do not have hormones in them. These pills are called "reminder" or “placebo” pills that they help remind you to take your pill every day and start your next pack on time

If you have 21-day packs .

Take 1 pill every day for 21 days in a row and then don’t take any pills for seven days. You’ll get your period during the fourth week while you aren’t taking any pills. It’s important to take every pill in a 21-day pack because there are no reminder pills. The hormone pills will prevent pregnancy even if you have sex during the week when you don’t take any pills. Start your next pack after not taking your pills for 7 days
Progestin Only Pills

You must take progestin only pills within the same 3 hours every day to be protected from pregnancy. For example, if you take your  pill at 12:00 p.m., taking it after 3:00 p.m. the next day puts you at risk for pregnancy

These pills only come in 28 day packs and all of them have hormones. You must take every pill in a progestin-only pack to be protected from pregnancy — there is no hormone-free week. You may get your period during the fourth week. You could also have bleeding on and off throughout the month (spotting), or get no period at all

You can start taking birth control pills as soon as you get them any day of the week and anytime during your menstrual cycle. But protecting from pregnancy depends on when you start and the kind of pill you’re using. You may need to use a backup birth control method (like condoms) for up to the first 7 days

 

Combination Pills 

 

If you start taking combination pills within 5 days after your period starts, you’ll be protected from pregnancy right away. For example, if you get your period Monday morning, you can start the pill anytime until Saturday morning and be protected from pregnancy right away

If you start combination pills any other time, you need to take the pill for 7 days before you’re protected from pregnancy. Use another method of birth control like a condom if you have sex during the first week on the pill

You’ll be protected from pregnancy after 48 hours on the pill and if you have sex during those first 2 days, use another method of birth control like a condom

,You must take these pills at the same time every day and if you take it more than 3 hours past your usual time
use a backup method of birth control for the next 48 hours

Side effects of the pills

 Most side effects usually go away in 2 to 3 months after you start the pills and some of them are headache, nausea, sore breast or spotting
