Wondering how many days ovulation lasts? Learn the facts, fertile window timing, and tips to boost conception chances in this 2025 fertility guide.
Understanding Ovulation
Ovulation is a key stage in the menstrual cycle where a mature egg is released from the ovary, ready for fertilization. For most women, this process happens once every cycle, and knowing exactly how many days ovulation lasts is crucial for pregnancy planning or natural contraception.
As of August 2025, advancements in fertility tracking have made it easier to pinpoint ovulation using apps, digital OPKs, and wearable devices. However, understanding the biology remains essential.
So, How Many Days Does Ovulation Last?
Ovulation itself — the release of the egg — typically lasts 12 to 24 hours. This is the time frame in which the egg can be fertilized. However, your fertile window is slightly longer because sperm can survive inside the female reproductive tract for up to 5 days.
Breakdown of the Fertile Window:
- Sperm lifespan: Up to 5 days
- Egg lifespan after release: 12–24 hours
- Total fertile period: Around 5–6 days in each cycle
How to Track Ovulation Accurately
To maximize your chances of conception (or to avoid pregnancy naturally), tracking ovulation is key. Here are proven methods:
1. Ovulation Predictor Kits (OPKs)
These test your urine for luteinizing hormone (LH) surges, which occur 24–36 hours before ovulation.
2. Basal Body Temperature (BBT)
Track your morning temperature daily. A small rise in temperature often signals ovulation has occurred.
3. Cervical Mucus Monitoring
Fertile cervical mucus becomes clear, stretchy, and slippery — similar to egg whites — just before ovulation.
4. Fertility Apps & Wearables
Modern tools like Flo, Ovia, and even some smartwatches can sync hormone and temperature data for more precise predictions.

Factors That Can Affect Ovulation Timing
While ovulation typically occurs around day 14 of a 28-day cycle, it can vary based on:
- Cycle length variations
- Stress levels
- Significant weight changes
- Medical conditions like PCOS or thyroid disorders
If your cycles are irregular, your fertile window might shift from month to month.
Signs You Might Be Ovulating
Your body gives clues when ovulation is near:
- Mild pelvic or abdominal pain (mittelschmerz)
- Breast tenderness
- Increased libido
- Changes in cervical mucus texture
- Slight rise in basal body temperature
When to Have Intercourse for Conception
Since sperm can live up to 5 days, having intercourse 2–3 days before ovulation and on ovulation day itself gives the highest chance of conception. Aim for:
- Every other day during the fertile window
- Daily intercourse in the 2 days before ovulation if possible
