It's pretty common for people to be confused about how birth control pills work. Here’s what it boils down to: birth control pills are made of hormones. Hormones are chemicals made in our bodies. They control how different parts of our bodies work.

. These are called combination pills. Some are progestin-only pills. Most women on the pill take combination pills.

Making cervical mucus
