Missed pill, can I be pregnant?

Patient: Hi, I take Cerazette every day as my birth control method. I had sex the night before last but missed my pill last night. I’ve just taken the missed tablet but I’m now about 20 hours late in taking it.. Will I be ok or is it possible I could fall pregnant?”

Doctor: Since you have missed just one pill, the chances of becoming pregnant are minimal. However, you may require to use an ad ded contraceptive measure (eg. condom) till your next periods.
