Ethinyl estradiol / norgestimate
"I've been on this pill for about 3 months. The only complaint I have about Sprintec is that it makes my breasts very tender and sore, usually three weeks out of the month. It hurts a lot, but it's not painful to the point where I have to stop everything. They have gotten larger, but I assume it's from the swelling. Other than that, it's a pretty great pill."
