I took portia birth control for a year. last month i started taking beyaz (drospirenone and ethinyl estradiol and levomefolate) birth control and now my period is 2 days late. is that normal?

Probably: A few days of cycle variation is not typically a problem. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy.

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.
