Pregnant Over 35? The Honest Guide to Fertility and Risk
Written by Jess Rosenberg, moode founder | Reviewed June 2026
In today's world, there are more choices for women than ever before. Thanks to contraception, equal opportunity, and the freedom to build a career and a life on our own terms, more of us are choosing to try for a baby later (hello, we've got sh*t to do). And we're far from alone in it: in Australia, women aged 35 and over now account for more than 1 in 4 births, around 28%, up from 23% a decade ago.So if you're over 35 and starting to think about family planning more seriously, there's a bit to get your head around. From fertility tracking to conception to what "high-risk" actually means, here are the honest answers to the questions you're really asking, minus the fear-mongering.
How to achieve a healthy pregnancy after 35
The short version: most women over 35 go on to have healthy pregnancies and healthy babies. Age does shift the odds in a few measurable ways, and knowing them puts you in a stronger position, not a more anxious one. Below, we walk through what actually changes, and what's genuinely within your control.
Can I have a healthy pregnancy after 35?
Yes. Plenty of women over 35 conceive and carry healthy pregnancies. It can take a little longer than it would have in your twenties, but the odds are far more encouraging than the panic-Googling suggests. Natural conception data shows that for women aged 35 to 39, the cumulative chance of conceiving is around 60% within one year and about 85% within two years of trying. In other words, most couples in this age group do conceive, it just may take a bit more time and patience.
If you're over 35 and have been trying for six months without success, that's the point at which it's worth having a chat with your GP or a fertility specialist (for women under 35, the usual guidance is twelve months). It doesn't commit you to anything. It just starts the conversation early, which is always an advantage.
What are the risks of pregnancy after 35?
It's true that pregnancy after 35 carries some added considerations, and miscarriage is the one most people ask about. Here the data is clear but far less frightening than the internet implies. A large 2019 study of more than 420,000 pregnancies found miscarriage risk was lowest for women aged 25 to 29 (about 10%), rising to around 17% at ages 35 to 39, and around 32% at 40 to 44. So the risk does climb with age, roughly tripling by your early forties, but it's worth holding onto the flip side: even at 40 to 44, the clear majority of recognised pregnancies do not end in miscarriage.
Beyond miscarriage, the chance of chromosomal differences increases with age, and conditions like gestational diabetes and high blood pressure become a little more common. None of this means a difficult pregnancy is a foregone conclusion. It means these are things worth understanding and monitoring, with a healthcare provider who knows your history and can give you personalised advice rather than a scary statistic with no context.
What can I do to support a healthy pregnancy after 35?
As you approach or pass 35, a few proactive habits genuinely help. None of them are revolutionary, and that's rather the point.
Stay active.
Regular movement supports overall health and helps maintain a weight that's supportive of fertility. Pilates, walking, swimming, dancing, whatever feels good and you'll actually keep doing.
Eat for fertility.
A balanced diet rich in fibre (beans and legumes), good-quality fats (salmon, nuts, seeds) and antioxidants (leafy greens, fruit and vegetables) supports reproductive health and egg health. Our fertility nutritionist's guide to conception goes deeper if you want the specifics.
Support your nutrient stores.
A daily prenatal helps cover the nutritional bases that matter most in the preconception window. moode's The Prenatal is a source of choline and zinc, which contribute to normal fetal development, plus iodine and a full B complex, in an iron-free, copper-free formulation.
Track your cycle.
Knowing when you ovulate is one of the highest-value things you can do when trying to conceive. It comes down to reading your body's signals, like changes in cervical mucus and basal body temperature, to find your fertile window. Our guide to ovulation tracking walks you through it.
Find a provider you trust.
Someone who offers friendly, personalised advice and keeps an eye on your health as you go. Think of them as an ally, not a gatekeeper, and know there are plenty of prenatal care options to suit how you want to do this.
Embracing the journey
Motherhood after 35 is its own kind of unique, and with the right support, knowledge and lifestyle choices, you can absolutely navigate this next chapter well. Every woman's journey is different. What matters most is finding the path that works for you and your family.
moode answers your questions about pregnancy after 35
Can you have a healthy baby after 35?
Yes. The majority of women over 35 go on to have healthy pregnancies and babies. Conception may take longer and some risks rise modestly with age, but with good prenatal care and healthy lifestyle habits, a healthy pregnancy after 35 is very achievable.
How long does it take to conceive after 35?
It varies, but natural conception data shows roughly 85% of women aged 35 to 39 conceive within two years of trying, and around 60% within one year. If you're over 35 and have been trying for six months without success, it's worth speaking to your GP or a fertility specialist.
Is 35 really a fertility cliff?
No. The idea of a sudden "cliff" at 35 is overstated. Fertility declines gradually with age rather than falling off a ledge on a particular birthday. The number 35 is simply where doctors start offering some additional monitoring and conversations.
Does miscarriage risk really go up after 35?
It rises gradually. Large population data puts miscarriage risk at around 10% for women in their late twenties, about 17% at 35 to 39, and around 32% at 40 to 44. So risk does increase with age, but the majority of pregnancies in these age groups still progress healthily.
What's the best supplement to take when trying to conceive over 35?
Look for a prenatal with active folate (such as calcium folinate), choline, iodine, zinc and a B complex, ideally started at least three months before trying. These nutrients support the preconception window when egg development and early fetal development are underway.
