Wonder if you can get pregnant on ovulation day?
Yep, you sure can
But it’s not the holy grail of conception. In reality, the three days leading up to ovulation offer the best odds of pregnancy.
Keep reading to learn your chances of getting pregnant on ovulation day – and every other day in your fertile window.
But first, let’s cover some basics.
Key Takeaways
- Your chances of conceiving are highest in the three days leading up to ovulation.
- Having sex on the day of ovulation yields a 20% chance of conception.
- Around 31% of women have irregular menstrual cycles, which makes predicting ovulation tricky.
- Most couples will get pregnant within a year of trying to conceive. Your chances of conception depend on your age, health conditions, and how often you have sex during your fertile window.
- Using a fertility monitor like Inito that measures LH, FSH, estrogen, and PdG helps pinpoint your fertile days and confirm ovulation. That way you know the best days to have sex.
- You can boost your chances of getting pregnant by maintaining a healthy lifestyle, avoiding sex during your luteal phase, and tracking and confirming ovulation.
Getting Pregnant 101
Midway through your menstrual cycle, one of your ovaries releases an egg. This is known as ovulation. Ovulation occurs roughly 12-14 days before your next expected period.
The key to getting pregnant is for sperm to reach the egg. If the sperm fertilizes the egg, this is known as conception. Conception is the first stage of pregnancy. However, it’s just step one.
For conception to be a success, the fertilized egg must travel to the uterine wall to prepare for implantation.
This usually occurs around 6 to 12 days after fertilization. Once a fertilized egg implants, your pregnancy officially begins.

What Are My Chances of Getting Pregnant on Ovulation Day?
This may come as a surprise, but sex on ovulation day without protection only offers a 20% chance of pregnancy. The good news is that the day of ovulation isn’t the only day you can get pregnant.
To help you understand, let’s do a quick refresher on your fertile window.
What Is the Fertile Window?
Your fertile window is the time during your menstrual cycle when you have the best chance of pregnancy.
It lasts for 6 days: the four days leading up to ovulation, your ovulation day, and the day after.
Sperm can remain alive in the reproductive tract for 4-5 days. But an egg only survives for around 12-24 hours after it’s released.
This means the more sperm on hand when an egg is released, the better your chances of conception.
That’s why it’s important to nail the timing of intercourse when you’re trying to conceive. And it’s why you don’t need to wait for ovulation day to do the baby dance.

What Are My Chances of Getting Pregnant Before and After Ovulation?
To get pregnant, you need to have sex during your fertile window. It’s that simple. Yet certain days during your fertile window offer a better chance of conceiving.
One study from Fertility and Sterility tracked the cycles of over 98,000 women over five years.
Here’s what they found:
As you can see, the day before ovulation offers the best chance of conceiving – NOT ovulation day.
In fact, even having sex three days before ovulation offers a better chance of getting pregnant than sex on ovulation day.
As the data shows, 27% of couples that had sex three days before ovulation got pregnant. Compare that to 20% who had sex on ovulation day.
So if you want to get pregnant, your best bet is to have intercourse in the days leading up to ovulation.
How Can I Tell When I’m Ovulating?
The easiest way is to track your ovulation. You can do this with an Ovulation Predictor kit (OPK) or a fertility monitor, like Inito. Here’s how they work.
Around 24-36 hours before you ovulate, Luteinizing Hormone (LH) surges. This triggers the release of an egg.
Ovulation predictor kits (OPKs) measure LH to detect the surge and predict when ovulation will occur. The problem is, by the time LH surges, a good chunk of your fertile window has passed.
This is where Inito can help. Inito measures LH, estrogen, PdG (urine metabolite of progesterone), and FSH on a single test strip.
Estrogen starts rising around 3-4 days before ovulation. By catching this rise, you get a better gauge of your entire fertile window, and thus you can maximize your chances of conception. Plus, unlike most ovulation tests that base results on thresholds, Inito measures your actual hormone values.
Another thing – while OPKs predict ovulation, they don’t confirm that it actually happened. However, progesterone and its metabolite PdG do.
After an egg is released, PdG and progesterone levels start rising. So to confirm ovulation, choose a fertility monitor like Inito that tests PdG.
Now that you know how to tell when you’re ovulating, let’s take a look at some factors that can affect conception.
Different Factors That Affect Conception
Around 75% of couples will conceive within a year of trying. There are a few factors that influence your chances of conception.
Age
Fertility peaks in your twenties and declines with age. One 2020 scientific review found that women under 30 have an 85% chance of conceiving within a year.
By age 30, your chances of conceiving within a year drop to 75%. That number falls to 66% at age 35, and 55% by age 40.

Health conditions
Certain health conditions can make it challenging to get pregnant, including:
Polycystic ovary syndrome (PCOS)
PCOS is a hormonal condition that causes the ovaries to produce high levels of androgens, such as testosterone. Many women with PCOS have irregular cycles and problems with ovulation. In fact, around 80% of anovulation infertility cases (meaning ovulation doesn’t occur) are due to PCOS.

Endometriosis
This is when tissue similar to your uterine lining goes rogue and grows outside your uterus. It can cause pelvic pain, abnormal cycles, and infertility. Roughly 6-8% of women have endometriosis. Yet around 20-25% of people with endometriosis have no symptoms. Meaning you could have it, without knowing!

Thyroid problems
When your thyroid hormones become imbalanced, it can disrupt your reproductive hormones. This can disturb your menstrual cycle and make it more difficult to get pregnant.
Frequency of sexual intercourse
No surprise here, but couples who have sex more frequently near ovulation are more likely to conceive. Most fertility experts recommend sex every day or every other day during the fertile window.
However, remember that the three days leading up to ovulation offer better chances of conception than the day of ovulation. That’s why getting a clear picture of your fertile window is crucial when trying to conceive.
How Can You Increase Your Chances of Conception?
Here are a few things you can do to up your odds of pregnancy:
Keep a healthy lifestyle
The better you and your partner take care of your health, the better your chances of conception. Eating a nutritious diet, exercising regularly, and maintaining a healthy BMI are good places to start.
Smoking and drinking can also harm fertility. So if you smoke or drink, consider quitting or cutting back at the very least.
Also, try to keep stress under control. Too much stress raises the stress hormone cortisol. This can decrease progesterone levels and make it more challenging to get pregnant. Set aside time for activities that help you recharge, whether that’s yoga, nature walks, journaling, or meditation.
And try not to let baby-making turn into a chore. Relax, have fun with it, and enjoy yourself!
Track ovulation properly
Remember, your best chance of getting pregnant is to have sex before ovulation day. So don’t wait for ovulation day to hit the sheets! Make the most of your entire 6-day fertile window.
Inito measures LH, estrogen, PdG and FSH to give you a complete picture of your fertile window. That way, you know exactly when to have sex to boost your pregnancy odds.
Skip sex during your luteal phase
If you’ve been TTC (Trying to Conceive) for a while without any luck, you may want to avoid sex during your peri-implantation window (around 5 to 9 days after ovulation).
The research is mixed, but some studies show sex during this period may disrupt implantation. So if you’ve tried everything and aren’t getting pregnant, you may want to play it safe.

FAQs
Maybe. As mentioned, an egg survives around 12-24 hours after it’s released. So while it’s possible, the chances are only 8-20%. That’s why your best bet is to have sex every day or every other day during your fertile window
Yep! As long as sperm fertilizes an egg, it’s possible to get pregnant. What is the success rate of getting pregnant on ovulation day?
As mentioned, your chances of getting pregnant on ovulation day from unprotected sex are 20%. But your chances of getting pregnant the day before ovulation are 42%. Meaning, it’s twice as easy to get pregnant on the day before ovulation compared to ovulation day.
If you’re tracking ovulation accurately and know when your fertile window is, there’s a good chance of getting pregnant if you have unprotected sex. But it can take some time. So don’t lose hope if you’re not successful in the first few cycles.
Unfortunately, no. An egg only survives for around 12-24 hours once it’s released.
While having intercourse on the same day that you ovulate doesn’t guarantee that you will get pregnant, your chances of pregnancy are still good. However, note that the highest chance of pregnancy is actually the day BEFORE you ovulate. For best results, try having sex every day or every other day during your fertile window (the 6 days of your cycle that you have the highest likelihood of conceiving).
Yes, many people have successfully gotten pregnant from having sex on ovulation day. According to a large research study by Fertility and Sterility, you have a 20% chance of conceiving if you have intercourse on the day of ovulation.
Yes, your fertility is high on ovulation day! The 6 days of your fertile window include the 4 days before ovulation, the day of ovulation, and the day after ovulation. But the day of ovulation is not your most fertile day. The days that you have the highest chance of conceiving are actually the two days before ovulation.
There are several signs that indicate that ovulation is just around the corner. These include extra wet cervical mucus, increased sex drive, and a surge in your LH levels. Some women also experience light cramping, pain (called mittelschmerz), bloating, or breast tenderness when they are ovulating.
There are also signs that ovulation has just taken place. These include a slight rise in your basal body temperature (BBT) by about 0.5 to 1 degree Fahrenheit and a rise in your levels of progesterone.
On ovulation day, you have a 20% chance of conceiving, but there are other days that have an even higher chance for conception! Here’s a look at how fertile you are (aka your chance of conception) each day of your fertile window:
- 4 days before ovulation: 18%
- 3 days before ovulation: 27%
- 2 days before ovulation: 33%
- The day before ovulation: 42%
- Ovulation day: 20%
- The day after ovulation: 8%
You are more fertile on your peak day (when your LH is surging) than you are on ovulation. The 2 days leading up to ovulation day are your most fertile days, with a 33% chance of conception 2 days before and a 42% of conception the day before ovulation. On ovulation day, your chances of conceiving are 20%.
Yes, women can get pregnant on ovulation day. If you have unprotected intercourse the day that you ovulate, you have around a 1 in 5 chance of getting pregnant.
There is actually only a 20% chance of getting pregnant during ovulation because of the window for sperm and egg survival. Male sperm can live inside the female reproductive tract for up to 5 days, and a released egg can only survive for 12 – 24 hours.
So if you don’t have sperm on the ready inside your uterus and you have intercourse too many hours after ovulation, there’s a chance the egg won’t be any good anymore. This means for a higher chance at conception, it’s best to have sperm waiting before you ovulate. That way, you don’t miss out on the window where the sperm and egg are both still alive and able to go through fertilization.
No, you will not have a 100% chance of getting pregnant if you are ovulating. The journey that the male sperm and female egg take to go through fertilization and eventually conception is pretty complex! Additionally, factors such as egg quality, sperm health, general lifestyle, and co-existing conditions also play a role.
Some signs that can help you know when ovulation is over include:
- Seeing a rise in your progesterone or PdG levels
- Seeing a slight rise (0.5 – 1 degree Fahrenheit) in your basal body temperature
- Beginning to notice symptoms like bloating, constipation, and extra tiredness (as your progesterone levels rise after ovulation)
- Noticing changes in your cervical mucus and vaginal discharge (less in quantity and thicker than prior to ovulation)
It can be hard to get pregnant even when you’re ovulating for a variety of reasons. Some of these include:
- Not timing intercourse for the best chances on your most fertile days
- The fertilized egg failed to implant
- You’re experiencing hormonal imbalances or reduced egg quality
- Chromosomal abnormalities (which can be a normal part of the reproductive process)
- Either you or your partner have an underlying condition affecting your fertility

One way to increase pregnancy chances on ovulation day is having sex closer to when the egg is first released. This is because an egg can only survive for about 12 – 24 hours, so if you wait too long to have sex on ovulation day, you may have missed your window. So to add to that first step, tracking when you ovulate is another way to increase your pregnancy chances.
For example, if you use the Inito fertility tracker, you’ll be able to track your 4 fertility hormones so you can pinpoint your most fertile days and confirm ovulation.
