There are many different brands of birth control pills, but only two main categories of pill—the mini-pill and the combination birth control pill. Both types contain hormones, so the biggest difference between them is how you use them and which hormones they contain. The mini-pill only contains progestin. Combination birth control pills contain both estrogen and progestin. Opill is a brand of mini-pill.
