At 5 weeks of pregnancy, the main option for termination is a medical abortion using pills, which is safe and highly effective when used under medical guidance. Another option is a surgical abortion done by a doctor, which is quick and typically completed within 10 minutes. Consult a gynaecologist before taking any step to ensure safety, correct dosage, and proper follow-up.

Pregnancy is most likely during the fertile window, which is usually about 5 days before ovulation and the day of ovulation. In a typical 28-day cycle, ovulation happens around day 14, so the safer time for unprotected intercourse is usually a few days after the period ends and after ovulation until the next period. However, cycles can vary, so this method is not completely reliable, and using proper contraception is the safest way to prevent pregnancy.

Pregnancy can be prevented using several methods, including barrier methods such as condoms, combined oral contraceptive pills containing oestrogen and progestin, progestin-only pills or injections, long-acting options such as hormonal implants and intrauterine devices, and sterilisation procedures. It is advisable to consult a healthcare professional to choose the safest and most effective method based on your health, convenience, and future fertility plans.
