What Is It?
Ovulating is a moment in your menstrual cycle when a mature egg is released from your ovary and begins its journey down the fallopian tube. It’s triggered by a surge in hormones, especially luteinizing hormone (LH), that tells your body the egg is ready.
Once that egg is released, it remains viable for fertilisation for only a short time typically between 12 and 24 hours. After that window passes, the egg can no longer be fertilised and will dissolve back into your body.
This is why, even though ovulation itself is short, understanding its timing is key if you’re trying to get pregnant.
Ovulation Timing in a Typical Cycle
Most menstrual cycles last anywhere from 21 to 35 days, and ovulation usually happens about 14 days before your next period begins. That’s why many people with a regular 28-day cycle ovulate around day 14 but not everyone has a textbook cycle.
Some women may ovulate earlier or later in their cycle, especially if their cycle length varies each month.
The Fertile Window Is Longer Than Ovulation Itself
Here’s the part that’s really important for conception: your fertile window extends beyond the hours that the egg is alive.
Sperm can survive in the female reproductive tract for up to five days once they enter it. That means even if ovulation itself only lasts around 12–24 hours, you can still conceive on the days before ovulation because sperm may already be waiting when the egg is released.
This fertile period generally spans about six days the five days leading up to ovulation plus the day the egg is released.
So, if you’re tracking fertility to conceive, it’s most effective to consider this entire window, not just the day of ovulation.

Why Ovulation Only Lasts So Shortly
The egg’s limited lifespan makes evolutionary sense. Once it leaves the ovary, it’s journeying toward the uterus and preparing to pair with a sperm cell. If fertilisation doesn’t happen within that sweet spot of 12–24 hours, the egg is no longer viable and will be reabsorbed a normal part of the cycle.
How to Track More Accurately
Many people use a combination of methods to understand when it might be approaching:
- Ovulation predictor kits (OPKs): These look for surges in LH that often happen 24–36 hours before.
- Tracking changes in cervical mucus: Fertile mucus tends to be clear and stretchy often compared to raw egg whites when ovulation is near.
- Monitoring basal body temperature: A slight temperature rise after ovulating can help confirm the event has occurred.
Might Not Happen?
It’s worth noting that sometimes ovulation doesn’t occur in a cycle at all a condition known as anovulation. This might happen due to stress, postpartum changes, breastfeeding, hormonal conditions like PCOS, or other health factors. If your periods are irregular or absent, it can be worth discussing with a healthcare provider.
A Gentle Reminder
You deserve care, patience, and encouragement as you navigate fertility and reproductive health. Knowledge brings clarity not pressure and understanding your ovulation timing is one step toward feeling more confident in your body.
