Answer
Dear Cat,

What happened in your situation? Did you start your period? Is there any possibility that you could be pregnant? Even if you take birth control, there is always a chance of pregnancy. No birth control method is 100% safe in preventing pregnancy. Write me at CHERYL51@aol.com and update me. Thanks.
