If you have been taking your birth control pills correctly & consistently, then you were protected. Some antibiotics will decrease the effectiveness of the birth control pills. We recommend either abstaining from sex or using condoms during the week you’re on the antibiotics and for at least 7 days after completion of them. Since you started antibiotics after you had sex, you do not have to be concerned about the effective the antibiotics have now. Continue to take your pills every day, and use a back up method as above.
Several things can cause a changes in your menstrual cycle. Stress, illness, medications, and lack of sleep can alter your period. Your period may come earlier or later than usual. You may have some irregular bleeding or spotting throughout this cycle. Hang in there, your period will usuallly return to normal within a month or two.
