Ovulation Calculator Baby Plan on Windows Pc

Ovulation Calculator & Fertility Tracker — predict your fertile window, track ovulation symptoms, and time conception using the Shettles method to conceive a boy. 100% free, private, and works offline.

📅 ACCURATE OVULATION CALCULATOR
Enter your last period date and cycle length to instantly see your ovulation day, fertile window, and next period. Our fertility calendar visualizes your entire cycle with color-coded fertile days, ovulation day, and optimal conception timing.

🎯 FERTILE WINDOW & FERTILE DAYS TRACKER
Identify your 6-day fertile window — the only days pregnancy is possible. Sperm survive up to 5 days, so intercourse before ovulation maximizes conception chances. The ovulation predictor highlights every critical day so you never miss your window.

👶 SHETTLE'S METHOD FOR CONCEIVING A BOY
The built-in Shettles method calculator pinpoints the ideal timing: intercourse 12–24 hours before ovulation may increase chances of conceiving a boy. Your "best boy day" pulses in green on the fertility calendar — impossible to miss.

📆 INTERACTIVE OVULATION CALENDAR

THE FERTILE WINDOW EXPLAINED
Your fertile window is the 6-day period ending on ovulation day. Having intercourse during these fertile days — particularly 1–2 days before ovulation — gives you the highest chance of pregnancy. Our fertility tracker helps you identify and act on these critical days with confidence.

THE SHETTLES METHOD
Developed by Dr. Landrum Shettles, this theory suggests timing intercourse close to ovulation may favor Y-chromosome sperm (boys) due to faster swimming speed. The app calculates your optimal "boy conception day" and highlights it on your calendar. While no method guarantees gender selection, many couples find this framework helpful for timing.
