The best method for birth control or avoiding pregnancy depends on individual preferences, health considerations, and lifestyle. Common methods include:

1. Condoms: Provide protection against both pregnancy and sexually transmitted infections (STIs).
2. Birth Control Pills: Hormonal pills that prevent ovulation and thicken cervical mucus.
3. Intrauterine Device (IUD): A small device placed in the uterus to prevent pregnancy.
4. Depo-Provera (Depo Shot): Injectable hormonal contraception.
5. Implant: A small rod inserted under the skin that releases hormones to prevent pregnancy.
6. Natural Family Planning: Monitoring menstrual cycles and fertility for timing intercourse.

It’s essential to consult with healthcare professionals to determine the most suitable method based on individual health, preferences, and lifestyle.
