Ortho Tri-Cyclen - pill - Just like your natural levels of hormones vary throughout your cycle, so do the hormonal doses in ORTHO TRI-CYCLEN, delivering three levels instead of just one. So you get the right amount of hormones throughout your cycle to prevent pregnancy—with a low dose. As you go through your normal cycle, every 28 days or so, the pituitary gland releases hormones that signal the ovaries to prepare an egg and send it to the uterus—to be fertilized. However, when you take ORTHO TRI-CYCLEN, which contains two types of hormones (norgestimate and ethinyl estradiol), it inhibits this process from occurring and, as a result, no egg is released. It also thickens the cervical mucus, making it difficult for sperm to enter the uterus. So it's easy for you to prevent pregnancy. (99% effective when taken correctly)
