This is my second month on birth control pills. My first period after starting the pills only lasted about 4-5 days, but i didn't start the next pack until the 8th day, as directed. I didn't miss any pills this month, but I did have sex without a condom. Now my period is already 2 days late. I heard that if you wait too long to start your pills (as in after your period) there is a high chance of pregnancy, is that true? Could I be pregnant???
