I took 1st pill of yaz (drospirenone and ethinyl estradiol) last monday.i took antibotics from the same monday till friday. friday i had sex. am i still protected bcz i took abtibiotics?

No: Antibiotics can interfere with birth control pills and make them less effective. Nothing you can do now and you will probably be okay. If you miss your period take a home ept. In the future use condoms in a cycle where you have taken antibiotics.

Depends: Antibiotics can decrease the effectiveness of the piill. It is recommended to use a back up contraceptive such as condoms while on antibiotics. Not too much you can do at this time. Keep taking pills as recommended.
