BCP ?'s: If you started your first pack of oral bcp's on the fifth day of a normal period, some bleeding or spotting usually occurs in the week following the last active pill (number 21). If you started the second pack on day 22, you will see no bleeding, as the level of hormones did not change. If you started pack #1 randomly (not on day 5 of your last period) , get a test for pregnancy.
