Quick Answers to Common Questions

❓ When are you least likely to get pregnant?

Answer: You are least likely to get pregnant during:

  • Days 1-3 of your period - No egg is present
  • 24-48 hours after ovulation - Egg is no longer viable
  • Late luteal phase - The week before your next period

However, remember that no days are completely "safe" as cycles can vary.

❓ Can you get pregnant during your period?

Answer: While less likely, yes, it is possible to get pregnant during your period, especially if you have:

  • Shorter cycles (21-24 days)
  • Longer periods (6+ days)
  • Irregular cycles

Sperm can survive up to 5 days in the female reproductive tract, so if you ovulate early, pregnancy is possible.

❓ How many days after ovulation are you least fertile?

Answer: You are least fertile from about 24-48 hours after ovulation until your next period begins.

The egg only survives 12-24 hours after ovulation, making this the period with the lowest fertility. This is why the luteal phase (days 15-28 in a typical cycle) is generally your least fertile time.

❓ What are the "safest" days to avoid pregnancy?

Answer: There are no completely safe days, but the days with the lowest pregnancy risk are:

  • During your period (especially days 1-3)
  • After ovulation (24+ hours after egg release)
  • Late luteal phase (week before next period)

Even these "safer" days are not 100% reliable due to cycle variations.

❓ How can you tell when you're least fertile?

Answer: Signs that indicate low fertility include:

  • Dry cervical mucus - No slippery, stretchy discharge
  • Lower basal body temperature - Below your post-ovulation rise
  • During your period - Menstrual bleeding
  • After ovulation - When you've confirmed ovulation occurred
  • Decreased libido - Lower sexual desire

❓ Why aren't "safe days" 100% reliable?

Answer: Several factors make natural family planning unreliable:

  • Cycle variations - Stress, illness, or lifestyle changes can affect timing
  • Early ovulation - Can occur unexpectedly
  • Sperm survival - Can live up to 5 days in the female body
  • Irregular cycles - Make prediction difficult
  • Hormonal changes - Can cause unexpected ovulation
