Short-acting oral contraceptives are a type of birth control pill that are typically started on the first day of the menstrual cycle. Starting the pill on the first day of the menstrual cycle ensures optimal contraceptive effectiveness and also helps confirm the beginning of the menstrual cycle.

Specifically, the first day of the menstrual cycle is defined as the first day of visible menstrual bleeding. Taking short-acting oral contraceptives on this day ensures that the medication begins working before ovulation occurs, effectively suppressing ovulation and preventing pregnancy. Additionally, these pills can thin the uterine lining, reducing the likelihood of implantation of a fertilized egg.

It is important to follow a doctor's advice regarding the proper method and dosage of short-acting oral contraceptives to ensure their safety and effectiveness. Furthermore, it should be noted that oral contraceptives do not protect against sexually transmitted infections; therefore, condoms or other protective measures should still be used during sexual activity.
