INSIGHT

Fertile Window Is Six Days

  • The fertile window is a moving six-day span: the five days before ovulation plus ovulation day.
  • Highest conception odds are the two days before ovulation and the day of ovulation, peaking the day before.
ADVICE

Act On The First Positive OPK

  • Use OPKs to predict ovulation but act when they first turn positive by having sex that day and the next.
  • Test midday or afternoon too because LH surges can be brief or missed with morning-only testing.
ADVICE

Use BBT To Confirm, Not Predict

  • Use basal body temperature (BBT) to confirm ovulation after it happens, not to predict it.
  • Track BBT trends over 2–3 cycles to learn your pattern and combine with OPKs and mucus to forecast future ovulation.
