How does Ortho Tri Cyclen Work?

As with most birth control pills on the market, they effect hormones in your body to inhibit the release of an egg during the days in between your cycle. In a normal monthly cycle, about 10 – 12 days after the last day of your period, an egg is released and thus, ovulation has occured. With the hormones in Tri Cyclen, the hormones ‘fake’ your body into thinking an egg has been released.
