While there are just two major kinds of birth control pills (COCPs and POPs), there are many different brands or versions of each kind of pill. Every brand of COCP will have the same hormones (estrogen and progesterone) in it. However, each brand has a different amount of hormones in it. Also, some brands change the amount of hormones given from week to week.
