🧠 How Ovulation Works

Ovulation is when an ovary releases an egg, making it available for fertilization. This is the time when conception is most likely.

Key Facts About Ovulation:

  • ⏱️ Occurs roughly midway through your menstrual cycle (around day 14 of a 28-day cycle)

  • 🌸 The fertile window lasts about 5–6 days (including the 24-hour egg lifespan)

  • 🩸 Hormones like LH (luteinizing hormone) and FSH (follicle-stimulating hormone) regulate ovulation

  • ⚡ Factors such as stress, illness, or irregular cycles can affect ovulation timing

Knowing your fertile days is crucial for couples trying to conceive.

🔬 How Ovulation is Calculated

Method 1: Calendar-Based

  • Uses cycle length and LMP to estimate ovulation

  • Works best for regular cycles

  • Fertile window includes 5 days before ovulation + ovulation day

Method 2: Basal Body Temperature (BBT)

  • Track slight temperature rise after ovulation

  • Helps confirm ovulation occurred

Method 3: Ovulation Predictor Kits (OPKs)

  • Detect LH surge in urine

  • Predicts ovulation 12–36 hours in advance

Our Ovulation Calculator combines cycle data and averages to provide a reliable estimate for most women.


⚖️ Factors Affecting Ovulation

Several factors can influence ovulation and fertility:

  • 🏋️ Stress or intense exercise

  • 🍎 Poor nutrition

  • 💊 Medications like hormonal contraceptives

  • 🩺 Medical conditions like PCOS or thyroid disorders

  • 🌙 Irregular menstrual cycles


🧮 Fertile Window and Timing

The fertile window includes:

  • 🌸 5 days leading up to ovulation

  • ⚡ Ovulation day itself

Example: If ovulation occurs on day 14 of a 28-day cycle:

  • Fertile window: Day 9 – Day 14

  • Best days to try: Day 12 – 14 for highest conception chances

Tracking your fertile window allows couples to plan intercourse strategically.


🧬 Signs of Ovulation

While ovulation calculators provide estimates, some women notice physical signs of ovulation:

  • 🌸 Mild pelvic pain or cramping

  • 💧 Increased cervical mucus (clear, stretchy, egg-white consistency)

  • ⚡ Slight increase in libido

  • 🩸 Breast tenderness

  • 🌡️ Basal body temperature rises slightly
