Trying to conceive? This Pregnancy Probability Calculator helps you understand your chances of getting pregnant during your current cycle by taking into account your ovulation day, the timing of intercourse, and your age.

Why Ovulation Timing MattersTiming is everything when it comes to conception. Ovulation typically happens about 14 days before your next period, and the few days leading up to it, your "fertile window", are your best shot. This calculator uses your last period date and average cycle length to estimate your fertile days, so you can plan intercourse when it matters most.
The Role of AgeFertility naturally declines with age, especially after 35. This tool adjusts your chances based on your age bracket, so the result reflects a more accurate range.Planning for Pregnancy: Lifestyle Modifications to Make NowIf you’re actively trying, a few lifestyle shifts can make a real difference:
  • Quit smoking and limit alcohol, as both can lower fertility for men and women.
  • Maintain a healthy weight, as extremes on either end can affect ovulation.
  • Take prenatal vitamins, especially folic acid, to support early pregnancy.
  • Manage stress, because high stress can mess with your cycle.
  • Get regular checkups and talk to your doctor if you’ve been trying for 6 months (if over 35) or a year (under 35) without success.
