What should I do if my period doesn't come after taking birth control pills?

Patient's question:

No

Doctor's answer:

Hello, your period is currently delayed by more than ten days. It could be pregnancy due to contraceptive failure, or it might be caused by endocrine disorders from taking emergency contraception. If your period is delayed, you can first test to see if you are pregnant. If you are not pregnant, you can go to the hospital for an ultrasound examination.
