Patient: I am on Beyaz birth control, and have been for around 3 years now. I have recently been on Amoxicillin for strep throat. I am aware that this antibiotic counteracts with Beyaz, so I used other contraception. However, the condom broke, so I felt it necessary to get Next Choice (Plan B alternative). It has been 5 days, am now off the antibiotics, and my birth control is now in the placebo pills. Should I be getting my period soon? I am getting worried.
