Understanding Missed Pills

Missing birth control pills is more common than you might think, and it doesn't automatically mean you're unprotected. The key is knowing what to do based on how many pills you've missed and when in your cycle it happened. This guide will help you navigate missed pills safely and confidently.

What Counts as a Missed Pill?

A missed pill occurs when you don't take your birth control pill within 24 hours of your scheduled time. This includes:

  • Complete miss - Forgetting to take a pill entirely
  • Late pill - Taking a pill more than 24 hours late
  • Vomiting - Throwing up within 2 hours of taking a pill
  • Severe diarrhea - Having diarrhea within 2 hours of taking a pill
  • Drug interactions - Taking medications that interfere with absorption

Protection Status

  • You're still protected from pregnancy
  • No need to use condoms or other backup methods
  • Continue your normal routine

Timing Considerations

When in Your Cycle Matters

Week 1 (Days 1-7)

  • Risk: Higher risk of pregnancy
  • Action: Use backup contraception
  • Reason: Body hasn't built up sufficient hormone levels

Week 2 (Days 8-14)

  • Risk: Moderate risk
  • Action: Use backup contraception
  • Reason: Approaching ovulation time

Week 3 (Days 15-21)

  • Risk: Lower risk
  • Action: May not need backup
  • Reason: Ovulation likely already suppressed

Placebo Week (Days 22-28)

  • Risk: No additional risk
  • Action: No special action needed
  • Reason: Placebo pills don't affect protection

Special Situations

Vomiting or Severe Diarrhea

If you vomit or have severe diarrhea within 2 hours of taking your pill, your body may not have absorbed the hormones properly. Treat this as a missed pill:

  • Take another pill from your pack immediately
  • Continue with your regular schedule
  • Use backup contraception for 7 days if you're in week 1 or 2
  • Contact your provider if vomiting/diarrhea continues

Drug Interactions

Some medications can interfere with birth control effectiveness:

Antibiotics

Most antibiotics don't affect birth control, but rifampin and griseofulvin can reduce effectiveness. Use backup contraception while taking these medications.

Anticonvulsants

Some seizure medications can reduce birth control effectiveness. Discuss with your provider about alternative contraception methods.

HIV Medications

Certain HIV medications can interfere with birth control. Use backup contraception and discuss with your healthcare team.

St. John's Wort

This herbal supplement can reduce birth control effectiveness. Use backup contraception while taking it.

Emergency Contraception

When to Consider Emergency Contraception

Emergency contraception (EC) may be needed if:

  • You missed 2 or more pills and had unprotected sex
  • You missed pills during week 1 or 2 of your cycle
  • You're unsure about your protection status
  • You had unprotected sex within 5 days

Types of Emergency Contraception

Plan B (Levonorgestrel)

  • Available over-the-counter
  • Most effective within 72 hours
  • Can be taken up to 5 days after
  • Works by preventing ovulation

Ella (Ulipristal Acetate)

  • Requires prescription
  • Effective up to 5 days
  • More effective than Plan B
  • Works by delaying ovulation
