HELP. could i be pregnant?

Zedd is an antibiotic from the azalide family. Azalides may interfere with the effectiveness of the contraceptive pill and it it recommended that you use another birth control method while taking the antibiotics. That being said, it doesn't guarantee that it will stop your birth control from working, just that it can. Since you shouldn't be ovulating right now, you are probably safe. Just be sure to use condoms if you have again while taking the antibiotic and seven days after stopping them.
