Yes : Because you were not on Yaz (drospirenone and ethinyl estradiol) long enough to provide any protection

Yes: Please use Plan B again, and please understand how contraceptives work and how they may fail. You need to be on Yaz (drospirenone and ethinyl estradiol) for a full cycle before it can act as a contraceptive. Until then please use barrier protection.
