Final answer:
If a woman forgets to take the pill for two days in a row, she should take emergency contraception as soon as possible to prevent pregnancy.
Step-by-step explanation:
If a woman forgets to take the pill for two days in a row, it can increase the risk of pregnancy. In this case, she should take emergency contraception as soon as possible. Emergency contraception works by preventing ovulation or fertilization, or by inhibiting implantation of a fertilized egg.
It is important to note that emergency contraception should not be used as a regular method of birth control. If a woman frequently forgets to take her birth control pills, she may want to consider using a different method that doesn't require daily adherence, such as an intrauterine device (IUD) or a contraceptive implant.
