In brief: Yaz (drospirenone and ethinyl estradiol)

Yaz (drospirenone and ethinyl estradiol) is a birth control pill that thins the lining and prevents ovulation.
Therefore, if you start it when your period begins, it should ovulation with the cycle. If this is the first time taking it, you should still use back up protection for 1 - 2 cycles until your body has adapted to taking it.
