Can I get pregnant two days after ovulation?

It’s very unlikely. By two days after ovulation, the egg is no longer viable. Sperm needs to meet the egg within 12–24 hours after it’s released for pregnancy to occur.

How do I know if I’ve already ovulated?

You can track ovulation through changes in your cervical mucus, basal body temperature, or by using ovulation test kits. A rise in temperature or a change in mucus texture usually indicates that ovulation has just occurred.

Is it better to have sex before or after ovulation to get pregnant?

It’s better to have sex before ovulation. Since sperm can live up to 5 days, they’ll already be present in your fallopian tubes when the egg is released, increasing the chances of fertilisation.

Can Sperm Survive Long Enough to Fertilise After Ovulation?

During the time you are trying to conceive (or attempting to prevent pregnancy), it is crucial to understand your fertility window and when your body is most fertile. Among the most popular questions that may come across your mind: Is it possible that sperm live long enough to fertilise an egg when ovulation has already occurred?

What Happens During Ovulation?

Ovulation is the process by which one of your ovaries releases an egg. This usually happens around the middle of your menstrual cycle, typically 14 days before your next period starts. However, this varies on an individual basis.

Once released, the egg travels down your fallopian tube. For pregnancy to happen, the egg needs to meet the sperm in the fallopian tube. But here’s the catch: the egg only lives for about 12 to 24 hours after ovulation.

So if you're wondering whether sperm can fertilise the egg after this period, the short answer is: No, not after the egg has disintegrated. But sperm itself can live longer inside you.

How Long Can Sperm Live Inside You?

Sperm can survive inside your reproductive tract for up to 5 days, depending on several conditions. If your cervical mucus is fertile (which it usually is around the time of ovulation), it helps sperm stay alive and mobile.

That means if you have sex a few days before you ovulate, the sperm may still be alive when your egg is released. This is one of the most common ways conception happens.

However, if you have sex after ovulation, you’re working with a much tighter window.

So, Can Sperm Fertilise After Ovulation?

Let’s be clear: Fertilisation can only happen if a healthy sperm reaches a healthy egg while it’s still alive, that is, during the 12 to 24 hours after ovulation.

If you have sex immediately after ovulation, there is still a small chance that sperm can fertilise the egg, but the chances reduce with every hour that passes.

If you wait more than 24 hours after ovulation, then the egg is no longer viable, and even if sperm reaches it, pregnancy cannot occur.

Why Is Timing So Important?

Timing your intercourse around ovulation is critical because of these basic facts:

Egg lives: 12 to 24 hours.
Sperm lives: Up to 5 days.

The most fertile period is considered to be the 5 days preceding ovulation and the day of ovulation itself. Having sex during this "fertile window" increases your chances of conceiving.

If you try to conceive after ovulation, especially after 24 hours, the chances become very low because the egg may no longer be alive.

Can You Still Get Pregnant After Ovulation?

Yes, but only if intercourse happens very soon after ovulation. If the sperm is introduced into your body during that 12 to 24-hour time frame when the egg is still alive, fertilisation can happen.

However, if you're having intercourse a day or two after ovulation, the likelihood of pregnancy is very low. By then, the egg is most likely no longer available.

What Can Affect Sperm Survival?

Not all sperm survive equally. The actual lifespan of sperm inside your body can depend on a few factors:

Cervical mucus quality: Fertile mucus protects and nourishes sperm.
Overall sperm health: Stronger, healthier sperm live longer.
Timing of intercourse: If timed poorly, sperm may die before the egg is released.
pH levels in the vagina: If too acidic, it can harm sperm.

Taking care of your health, avoiding smoking and alcohol, and staying hydrated can also help in supporting sperm and egg health.

How Can You Track Ovulation Accurately?

To maximise your chances, you need to know exactly when you’re ovulating. Here are some ways you can do that:

Ovulation predictor kits (OPKs): These detect the LH surge before ovulation.
Basal body temperature (BBT): Your temperature slightly increases after ovulation.
Cervical mucus tracking: It becomes clear and stretchy when you’re most fertile.
Calendar method: Helps estimate ovulation based on your past cycles.

If you're trying to conceive, try to have sex during the few days leading up to ovulation and on ovulation day. That way, the sperm is already there when the egg arrives.

So, can sperm live long enough to fertilise after ovulation?

Only if intercourse happens very soon after ovulation, within the egg’s short 12 to 24-hour lifespan. However, your best chances of conceiving a child are having intercourse before ovulation or on the day of ovulation.

If you’re trying to conceive, track your cycle closely and aim to have sex during the fertile window. If you’re trying to avoid pregnancy, don’t rely on timing alone; ovulation can sometimes be unpredictable.

Understanding how your body works empowers you to make informed decisions about your fertility, whether you're trying to conceive or prevent pregnancy.
