It is not possible to prevent pregnancy naturally after a week has passed since unprotected intercourse. Once sperm has reached an egg, the fertilization process has begun, and a pregnancy is underway.
While there are various natural family planning methods, such as the rhythm method or the symptothermal method, these methods focus on predicting ovulation and avoiding intercourse during the fertile window. They are not designed to prevent pregnancy after intercourse has already taken place.
The only reliable ways to avoid pregnancy after unprotected sex are:
- Emergency contraception: This includes pills like Plan B or Ella, which work by delaying or preventing ovulation. They are most effective when taken within 72 hours after sex, but the earlier the better.
- Medication abortion: This involves taking pills to end a pregnancy, and it is typically an option up to 10 weeks of gestation.
It is important to consult a healthcare professional for advice on pregnancy prevention and options.
