A typical menstrual cycle lasts between 21 and 35 days, with the average being 28 days. The cycle is divided into four phases:
Menstrual Phase (Day 1-5): This is when you have your period.
Follicular Phase (Day 1-13): The body prepares to release an egg.
Ovulation Phase (Day 14): The most fertile time of the cycle.
Luteal Phase (Day 15-28): The body prepares for pregnancy or another cycle.
Your fertility peaks during the ovulation phase. Ovulation typically occurs about 14 days before your next period starts. If you have a 28-day cycle, this means ovulation happens around Day 14.
Your fertility window includes:
The five days leading up to ovulation
Ovulation day itself
The day after ovulation
Since sperm can live in the female reproductive tract for up to five days, having unprotected intercourse in the days before ovulation increases the chances of fertilization. However, once ovulation occurs, the egg only survives for about 12-24 hours, making this a critical time for conception.
There are several ways to determine when you are most fertile:

Tracking Your Cycle - Using a calendar or a period-tracking app can help you estimate your ovulation day.
Basal Body Temperature (BBT) Monitoring - Your basal body temperature slightly rises after ovulation. By taking your temperature every morning before getting out of bed, you can identify patterns in your cycle.
Cervical Mucus Observation - As ovulation approaches, cervical mucus becomes clear, stretchy, and egg-white-like, which helps sperm travel more easily.
Ovulation Predictor Kits (OPKs) - These test strips detect the luteinizing hormone (LH) surge that occurs 24-36 hours before ovulation, signaling your most fertile time.
Certain factors can impact when and how often you ovulate, including:
Stress
Hormonal imbalances
Polycystic Ovary Syndrome (PCOS)
Weight fluctuations
Medical conditions
Age
If you experience irregular cycles or have difficulty tracking ovulation, consult a doctor for further evaluation. By understanding your cycle and using fertility tracking methods, you can better predict your ovulation window, whether for conception or reproductive health awareness.
