If you’ve already had twins, your chances of having them again are higher than average—especially with fraternal twins and a family history of multiples. Genetics, age, and fertility treatments all play a role, but identical twins remain a random occurrence.

Will I Get Pregnant with Twins Again?
Finding out you’re expecting twins is often the surprise of a lifetime. Many parents of multiples wonder: “If I had twins once, will I get pregnant with twins again?” The short answer is yes—it’s possible, but not guaranteed. Let’s break down the science, statistics, and real-life factors that influence your chances.
Genetics: The Strongest Predictor
Your family history plays a big role. Research shows that having fraternal (dizygotic) twins runs in families, especially on the mother’s side. If you ovulate more than one egg per cycle—a trait that can be inherited—your chances of twins are higher.
- Example: If your mother, grandmother, or sisters had fraternal twins, you may be more likely to conceive twins again.
- Identical twins, however, are not genetic. They occur when one fertilized egg splits, which is considered a random event.
The Odds After Having Twins
Statistically, women who have already had twins are more likely to conceive twins again compared to women who haven’t. According to the American Society for Reproductive Medicine:
- The overall chance of naturally having twins is about 1 in 250 pregnancies.
- The average chances of having twins again are around 1 in 100 if the previous twins were identical, and 1 in 20 if the previous twins were fraternal.
- For women who have already had fraternal twins, the odds increase significantly, though exact percentages vary. The numbers above are estimates.
In other words, your body has already shown it can release two eggs in one cycle—so it may do it again.
Factors That Influence Your Chances
Several factors can increase the likelihood of having twins more than once:
- Age: Women over 35 release more follicle-stimulating hormone (FSH), increasing the chances of double ovulation.
- Number of Pregnancies: The more pregnancies you’ve had, the higher your odds of conceiving twins naturally.
- Body Type: Taller and higher-BMI women statistically have higher rates of twin pregnancies.
- Fertility Treatments: IVF or ovulation-stimulating medications raise the chance of twins or higher multiples.
Real-Life Example
Many twin parents share stories of surprise when they conceived twins a second (or even third) time. For instance, some families documented online describe having fraternal twins in their first pregnancy and again in their third—demonstrating how genetics and repeated ovulation can play a role.
Can You Influence the Chances?
While you can’t guarantee another set of twins, a few factors might slightly increase your odds:
- Conceiving in your mid-to-late 30s.
- Having a higher-calorie or dairy-rich diet (some studies suggest this links to higher twin rates).
- Family history of fraternal twins.
That said, much of it still comes down to biology and luck.
Bottom Line: Will I Get Pregnant with Twins Again?
If you’ve already had twins, your chances of having them again are higher than average, especially if they were fraternal twins and you have a family history of multiples. But it’s far from certain—many twin moms go on to have singleton pregnancies, and some are surprised with multiples again.
If you’re here asking that question, and it’s actually because you’re scared, I’ll share some thoughts that might help you. You might be searching for a definitive answer. Some way of knowing whether or not you should try for “one more.” A way of predicting with 100 percent certainty, that if you try for one more, that you’ll only get one. Because, even though you love your twins, you’d really love to just have a singleton next time. And you’re afraid you can’t go through another twin pregnancy.
If you have always envisioned having two children but more than one pregnancy experience, consider if having the two children you hoped for is enough? Or, do you feel like something is still missing? If something feels like it’s incomplete or missing within your family, pray on it. God gives us the answers we’re searching for, we just have to be still and listen.
What I do know is this — if you want more kids, whether that be one more or many, you will never regret trying. And if you happen to have twins again, just know that it was meant to be, and we are here to support you every step of the way, no matter what!
FAQs – Will I Get Pregnant With Twins Again?
1. Am I more likely to have twins again if I already had them once?
Yes. If you’ve already had fraternal twins, your chances are higher than average because your body may release more than one egg per cycle. Identical twins, however, remain a random event.
2. Does having identical twins once mean I could have them again?
Identical twins are not linked to genetics and are considered a rare, random occurrence. While it is possible to have them again, the odds don’t increase after one set.
3. Does age affect my chances of having twins again?
Yes. Women over 35 produce more follicle-stimulating hormone (FSH), which can cause multiple eggs to release during ovulation, increasing the chances of fraternal twins.
4. Do fertility treatments increase the odds of twins again?
Absolutely. Treatments like IVF, Clomid, or gonadotropins significantly raise the chances of multiples because they stimulate the ovaries to release more than one egg.
5. Can lifestyle or diet make me more likely to conceive twins again?
Some studies suggest that women who consume dairy or have a higher-calorie diet may have a slightly higher chance of twins, but genetics and biology remain the main factors.
