Calculate your fertile window and ovulation date to optimize your chances of conception. Track your cycle and find the best days to try for pregnancy.
This helps calculate when your next ovulation will occur
Typical range is 21-35 days. Average is 28 days.
Menstrual Phase (Days 1-5)
Your period begins. Estrogen and progesterone levels are low.
Follicular Phase (Days 1-13)
Eggs begin to mature. Estrogen levels rise, preparing for ovulation.
Ovulation (Day 14)
A mature egg is released. This is your most fertile time.
Luteal Phase (Days 15-28)
Progesterone rises to prepare the uterus for potential pregnancy.
Track Your Signs
Monitor basal body temperature, cervical mucus, and ovulation tests for accuracy.
Optimal Timing
Try every other day during your fertile window for the best chances.
Healthy Lifestyle
Maintain a healthy weight, reduce stress, and take prenatal vitamins.
Remember: Sperm can live up to 5 days, so your fertile window is longer than just ovulation day.
