Pregnancy in Your 30s – Facts on Body, Mind, and Baby

I don’t have children yet. I plan on for this year. However, I am very aware of all the info about having kids after 35. I am 36, and it does weigh on my mind. But life has lead me to this time and my life, and trying to conceive at this age.

All of my girlfriends have children, so I hear about it a lot that my time is running out, or my eggs will be rotten. Luckily, I have not had children bases on what my friends think, and have done what my husband and I think is right.

I know a lot of women in our age group are waiting, and I also know a lot of women that have healthy babies well into their 30s and into their 40s naturally.

Information is power, even if some of these facts are not pretty to read, it is still good to know. It will not scare me, but I think if you are thinking of having your first baby, second, third or more, it is still good to know what to expect with your mind, body and baby.

Pregnancy in Your 30s - Facts on Body, Mind, and Baby

Don’t miss the good news at the bottom of the article.

Ages 30 – 34

Fertility begins to decline at age 30, but this change happens gradually, over the next five years or so. If you need infertility treatment, your chances of success are higher than they are for an older woman. For women under age 35 the success rate of in vitro fertilization (IVF), for example, is 25 to 28 percent; for those over age 40, that rate drops to 6 to 8 percent. One study found that the rate of cesarean sections was close to two times higher among women ages 30 to 34 than among those in their 20s, although doctors don’t know why.


“Women who have been fully involved in their job in their 20s often feel emotionally ready to start a family as they enter their next decade,” says Glazer. “And they have the energy and the resources to do it. But they may also feel pulled in different directions. They worry about whether they’ll be able to return to their work life — or whether they’ll even want to.”


The miscarriage rate is 11.7 percent. By age 30 your risk of having a baby with Down syndrome is 1 in 952, and a baby with any chromosomal abnormality, 1 in 385.

Ages 35 – 39

Fertility continues to decline after age 35, and it takes a nosedive at age 38, says Benjamin Younger, M.D., executive director of the American Society for Reproductive Medicine, in Birmingham, AL. “The decline is due mostly to the fact that the woman’s eggs are aging, and they become more difficult to fertilize,” he adds.

Up until age 35, most doctors suggest that couples have unprotected intercourse for a full year before seeking infertility treatment; that time period is reduced to six months for women over 35. “The greatest problem for infertile couples is delayed treatment, because there’s a big difference in success rates between a woman in her late 30s and one in her early 40s,” says Ruth Fretts, M.D., clinical instructor of obstetrics and gynecology at Harvard Medical School. “In fact, many infertility clinics won’t accept patients if they’re older than 39 or 40.”

The risk of high blood pressure during pregnancy is about double for women over 35 compared with younger ones; hypertension affects about 10 to 20 percent of pregnant women in this age group. Gestational diabetes is two to three times more common in women over age 35 than in younger women, and recent studies show the risk is even higher if the woman has gained weight over the years.

The chance of having a cesarean section is about twice as high for women ages 35 to 39 as for those in their 20s, possibly because labor tends to take longer in older women. “When the second stage of labor surpasses two hours, obstetricians often intervene and do a C-section to reduce stress on the fetus,” says Gertrud Svala Berkowitz, Ph.D., professor of obstetrics and gynecology and reproductive science at the Mount Sinai School of Medicine in New York City.


This is the age when your doctor might recommend amniocentesis or some other prenatal screening — which for many women is anxiety-provoking while they await results — because the risks of having a baby with Down syndrome or another type of chromosomal disorder begin to rise significantly.


The chance of having multiple births, especially twins and even triplets, increases significantly in your late 30s (and early 40s). “This is probably due to the fact that the hormonal stimulation of the ovaries changes slightly as a woman ages, increasing the chances that they’ll release more than one egg,” says Dr. Younger. “It could be Mother Nature’s way of compensating for the fact that more eggs are likely to be defective.” Women who take fertility drugs are also at higher risk of multiple births because the drugs stimulate the ovaries to produce more eggs. Even so, the chance of twin, triplet, or other multiple births is still relatively slim.

The miscarriage rate rises after age 35 to close to 18 percent. Rates of stillbirths are about twice as high among older pregnant women than younger ones, according to recent studies, although the reasons are unknown.

In Your 40s
We are just going to give the good news.
A recent study shows that women over 40 who have babies without help from fertility drugs or other assisted reproductive technologies tend to live longer than those who don’t. Why? One theory is that estrogen, which is still produced in abundance in fertile women, has life-lengthening effects on the heart, bones, and other organs.

Statistics show that once a woman has gotten pregnant, if she takes good care of herself and if prenatal screening tests are negative, she’s much more likely to deliver a healthy baby than not — regardless of her age. The rate of fetal deaths has dropped by about 70 percent since the 1960s. That’s great news for all pregnant women.

    This post hit sooooo close to home! I am 30, and childless. My hubby and I have decided to start trying for baby number 1, but we’re not fanatical about it. Everyone else, however, is waiting for this miraculous event to happen….so much pressure! I’ve decided that it will happen when God wants it to happen. And if that’s much further into 30, then so be it! Such an informative post! Thanks for sharing!

    May I respond to TheProDiva? You and your hubby have the perfect attitude about this…I assume”everyone else” equals parents, friends and family…I hope they will back off and let you guys make your own decisions in your own time. Best of luck!

    I’m 30 and want to wait 3/4 years yet to try for a baby. At the moment I have nothing to offer a baby: I’m in rented accommodation, no stable career etc. Surely the point of having a child is not simply because you want one, but because you look at your life and think that you actually have something to offer a new life.

    I had my first at 29 and I’m expecting my second now at 33. This time around has been so different. I got pregnant with my first within 4 months, and this time it took more like 9 months, longer if you count my second pregnancy which sadly ended in miscarriage. It’s hard to think that 4 years could make that much of a difference on a body, but it really does. I’m glad we did this when we did, no regrets. But it’s just tough.

    @Very Bloggy Beth – Thanks for sharing and congratulations! I’m am definitely getting nervous the longer we wait, but it also comes down to the right time for us. But you’re right, your body does make a lot of changes within that 5 – 6 year time frame.

    I had my first baby at 25 and didn’t have another until I was 33. Of course I would never take back my first son but I can tell you that being a mom in your 30’s is so much easier!! Well the pregnancy wasn’t easier but my financial, emotional state was so much better than my 20’s. Even my patience level is better. I tell all my younger friends, nieces etc to WAIT!!

  7. says

    I was 35 with my first and 36 with my second. Pregnancy is tough but it is so worth it in the end. And waiting until you are ready makes it that much better….because let me tell you for all the wonderful moments there are still some trying ones too and if you are not ready those trying moments could be that much harder. Good for you for not caving to peer pressure and you are right you have time….so take it. Enjoy!!!! You will make a lucky baby very happy one day. Have a great day!

    Hi Tara,

    All pregnancies should be planned, because unplanned pregnancy are at greater risk of preterm birth and low birth weight. It’s imperative for you to learn preconception care to determine whether you’re physically and mentally prepared for the long journey ahead. Think about pregnancy planning as preventive medicine for you and for the child you’re planning to conceive.
