Planning for Parenthood: A Guide to Preconception Health

WORDS: Supplied Material PHOTOGRAPHY Supplied

Preconception health is everything you do before you start trying to conceive, not after the test turns positive. It’s easy to skip past this stage and go straight to timing and ovulation apps, but the groundwork actually matters. What you do in the months beforehand can shape how the pregnancy goes and how healthy your baby is from the start. Here’s what preconception health actually covers: the GP visit worth booking early, the fertile window, the supplements, and the everyday habits worth changing first.

Start With A Preconception Health Check

A preconception health check is just a GP appointment, but focused on your health before pregnancy rather than during it. Book three to six months before you start trying, if you can. That’s enough time to go through your medical history, check whether your vaccinations for things like rubella and chickenpox are up to date, catch up on cervical screening if it’s due, and talk through genetic carrier screening for conditions such as cystic fibrosis or fragile X syndrome.

Take regular medication? This is the appointment to review it properly. Some medicines are fine through pregnancy. Others aren’t. Your GP can help you plan any changes safely, rather than you stopping something suddenly on your own.

Get To Know Your Fertile Window

Once the check-up’s ticked off, timing is the next piece. Ovulation happens roughly midway through a typical cycle: day 14 in a 28 day cycle, give or take, with the fertile window running through the few days before it and the day itself. Sperm can survive up to five days in the reproductive tract, which is why intercourse a few days before ovulation still has a real shot at leading to conception.

Tracking doesn’t need to turn into a project. Some people watch their cervical mucus, which gets thinner and more slippery close to ovulation. Others use an app, a calendar, or a predictor kit from the pharmacy. Plenty skip tracking altogether and just go with every two to three days across the cycle. Honestly, that works about as well for a lot of couples, minus the pressure of hitting one exact day.

Everyday Habits That Support Fertility

Diet, weight, lifestyle: all of it feeds into preconception health, for both partners, not just one. A varied diet with plenty of vegetables, fruit, wholegrains, legumes and lean protein supports your general health heading into pregnancy. If your BMI is over 30, even a modest amount of weight loss beforehand can improve outcomes.

Smoking, vaping, recreational drugs, alcohol: all worth stopping before you start trying, not just once you’re pregnant. Alcohol carries risk at any stage of pregnancy, and because early pregnancy isn’t always obvious straight away, it’s simpler to cut it out while trying rather than wait for a positive test. Stress is trickier. Managing it where you can is worth the effort, even though it’s rarely fully within your control during this particular stretch of life.

Two Supplements Worth Starting Early

Folic acid is the one most people have already heard of, and for good reason. Taking 400 micrograms a day, starting around 12 weeks before you begin trying and continuing through the first trimester, reduces the risk of neural tube defects like spina bifida. Some people need a higher dose depending on their medical history, so check with your GP rather than assuming the standard amount applies to you.

Iodine is the one people forget. It supports your baby’s brain and nervous system development, and most people are advised to take 150 micrograms a day. Got a thyroid condition? Talk to your GP before starting an iodine supplement, since the right dose can depend on how your thyroid’s functioning.

Your Partner’s Health Counts Too

Preconception health isn’t only about the person carrying the pregnancy. Sperm health responds to a lot of the same things: smoking, alcohol, weight, certain medicines, plus factors like heat exposure and some medical conditions. Where possible, it’s worth both partners going along to the preconception check-up, since family history and genetic carrier screening matter on both sides.

When To Ask For Extra Help

Most healthy couples conceive within six to twelve months of trying. For younger couples, it can genuinely take the full year with nothing actually wrong. As a general guide, see your GP if you’re under 35 and haven’t conceived after 12 months, or over 35 and haven’t after six. From there, your GP can review your history and refer you on if that’s the right next step.

A referral to a specialist fertility clinic like Adora Fertility usually means further testing first, to understand what’s going on, then a conversation about the treatment options that make sense for you.

You don’t need every answer before you start trying. Preconception health is really just about handling what you can ahead of time: medication reviews, vaccinations, a folic acid supplement, so you’re not troubleshooting all of it once you’re already pregnant. A GP appointment a few months out is usually the easiest place to start.
