How can I use progestin-only contraception (progestin-only pill (POP)) to delay my period for a trip?

Using Progestin-Only Pills to Delay Menstruation for a Trip

Norethindrone (5 mg three times daily) is the most effective option for delaying your period for a trip, with significantly less breakthrough bleeding compared to combined oral contraceptives when started before cycle day 12. 1

How to Use Progestin-Only Pills to Delay Your Period

Timing and Dosage

• Start norethindrone acetate 5 mg three times daily (15 mg total per day)
• Begin taking the medication on or before day 12 of your menstrual cycle for optimal results
• Continue taking the medication until you want your period to begin (typically after returning from your trip)
• Expect your period to start 2-3 days after stopping the medication

Effectiveness and Considerations

• Only 8% of women using norethindrone experience breakthrough bleeding compared to 43% using combined oral contraceptives 1
• Progestin-only pills can be started at any time if it is reasonably certain you are not pregnant 2
• If starting more than 5 days after your period began, use backup contraception (condoms) for 2 days 2

Potential Side Effects and Management

Common Side Effects

• Temporary weight gain (resolves after stopping the medication) 1
• Heavier withdrawal bleeding when you stop taking the medication 1
• Irregular bleeding patterns (though less common with norethindrone at this dosage) 3

Important Precautions

• If you experience vomiting or diarrhea while taking the pills:
  • Continue taking pills daily at the usual time if possible 2
  • Use backup contraception until pills have been taken for 7 consecutive days after vomiting/diarrhea resolves 2
  • Consider emergency contraception if vomiting occurred within the first week of pills and you had unprotected intercourse 2

Advantages of Using Progestin-Only Pills

• Higher satisfaction rates compared to combined oral contraceptives for period delay (80% of women would choose this method again) 1
• Faster return to fertility after discontinuation 1
• Safe option for women who cannot take estrogen-containing contraceptives 3
• Can be used by breastfeeding women 4

Important Considerations

• This is an off-label use of progestin-only pills
• Norethindrone at this higher dose (15 mg daily) is specifically for short-term use to delay menses
• Regular progestin-only contraceptive pills contain lower doses and would not be as effective for delaying periods
• Consult with your healthcare provider before starting this regimen, especially if you have any medical conditions or take other medications

Remember that while this method is highly effective for delaying your period, it does not protect against sexually transmitted infections, so use barrier methods if needed.
