How do you know if you're pregnant if you don't get a period on the birth control pill?

The Birth Control period, as you've notice, can make your period so light that you don't notice one at all. This situation is not a medical concern, but some women find a monthly period of bleeding reassuring. If you find it anxiety-provoking to have no withdrawal bleeding on the pill, talk with your health care provider about changing to a different pill that's more likely to lead to bleeding.
