  • You want to switch methods
  • You have questions about effectiveness or use

When to See a Doctor

Consult a healthcare provider to:

  • Discuss contraception options
  • Get a prescription for hormonal methods
  • Have an IUD or implant inserted
  • Address side effects or concerns
  • Get fitted for barrier methods
  • Discuss emergency contraception

Choosing the Right Method

Consider:

  • Effectiveness: How well it prevents pregnancy
  • Convenience: How easy it is to use
  • Side effects: What side effects you're comfortable with
  • STI protection: Whether you need protection against STIs
  • Reversibility: Whether you want to be able to stop easily
  • Cost: What you can afford
  • Health considerations: Your medical history and health conditions

Important Considerations

Effectiveness

  • "Perfect use" means using the method correctly every time
  • "Typical use" reflects real-world effectiveness
  • Long-acting methods tend to be more effective
  • Combining methods (like condoms + hormonal method) increases protection

STI Protection

  • Only condoms provide protection against STIs
  • Other methods prevent pregnancy but not STIs
  • Consider using condoms even with other methods if STI protection is needed

Side Effects

  • All methods can have side effects
  • Side effects often improve after a few months
  • Different methods may have different side effects
  • Discuss concerns with your healthcare provider

Getting Started

  1. Research: Learn about different options
  2. Consult: Talk to a healthcare provider
  3. Consider: Your needs, lifestyle, and health
  4. Try: Start with a method that seems right for you
  5. Evaluate: Give it time, but don't hesitate to switch if needed

Special Situations

After Childbirth

  • Some methods are safe while breastfeeding
  • Discuss timing and options with your healthcare provider

During Menopause

  • Some methods may not be needed
  • Hormonal methods may have additional benefits
  • Discuss options with your healthcare provider

With Medical Conditions

  • Some conditions affect which methods are safe

Remember, contraception is a personal choice. There's no one-size-fits-all solution. Work with your healthcare provider to find the method that works best for your individual needs, health, and lifestyle.
