I am on beyaz (drospirenone and ethinyl estradiol and levomefolate) birth control and last month i had a period twice...could it be because my pack i had for that month got ruined and i couldnt take it ?

Yes: The effect of the birth control pill depends on maintaining the hormone level in your blood. That means you have to take the pill every day at the same time. If you miss a pill, are late taking it, or if something else changes that level (like if your pills were damaged ) , you may have 'breakthrough' bleeding.

Please discuss this with your Gynecologist who has your complete medical history. If you are not confident with your Doctor please see another for a second opinion.
