Fertility After Your Period: When Can Conception Occur?

Yes, pregnancy is possible shortly after menstruation.

Typical 28-day cycle:

  • Period: Days 1–7
  • Ovulation: ~Day 14
  • Fertile window: Days 9–14 (5 days pre-ovulation + ovulation day)
  • Thus, fertility begins ~3 days after period ends.

Cycle length variation shifts ovulation. Track with OPKs, cervical mucus, or BBT for precision. Sperm survive 5 days; egg survives 12–24 hours.
