The "Fertile Window" are the days in your cycle when intercourse is most likely to result in pregnancy. This fertile window last for 6 days — it begins 5 days prior to ovulation and lasts until the day of ovulation. Your most fertile days are the 4-5 days before and the day of ovulation.

Improve Your Chances Of Getting Pregnant

  • Having sex the day after ovulation is unlikely to improve your chances of getting pregnant.
  • Increasing amounts of estrogen in the cervical mucus and reproductive tract of a women approaching ovulation generally allows the sperm to live for up to 6 days.
  • Studies have shown that even in women with regular cycles, ovulation can possibly happen any time, so "timing" of intercourse has never been shown to improve your pregnancy chances. You are probably not improving your chances of getting pregnant if you wait for intercourse until the temperature goes up or the OPK has become positive. You may already have ovulated by that time, and sex after ovulation is unlikely to get you pregnant.
  • In the past, couples trying to conceive (TTC) were told to have sex once every other day during their fertile days. Recent studies have shown that the average couple who is trying to conceive should have sex regularly 2-3 times a week, every week because you don't know exactly when ovulation happens.
