Trying for a Baby in the Next 3–6 Months?

Here's Where I'd Start

If a baby is on your radar for the next few months, there's a window right now that matters.Eggs take around 90 days to mature before ovulation. That means the egg you conceive with in three months' time is being shaped by what you're doing today: what you're eating, how you're sleeping, how stressed you are, even what's in the products around your house.

So if you came to me now, planning to try for a baby in the next 3-6 months, here's what I'd actually be looking at with you.

Start with your bloods

Before anything else, I'd want to see where you're starting from. Folate, B12, iron, vitamin D, iodine, and a full thyroid panel (TSH, FT4, FT3 and TPO antibodies) are the non-negotiables.

Recent UK data shows 83% of women aged 16-49 have folate below the level associated with the lowest risk of neural tube defects, and iodine insufficiency is common in women of childbearing age too.

Thyroid health deserves its own mention here. Even mild, "borderline" thyroid dysfunction can reduce conception rates and increase miscarriage risk, and the ideal TSH range for conception (roughly 1.0-2.5 mIU/L) is narrower than the standard reference range your GP might use. Getting this checked properly, rather than assumed "normal," is one of the most important things you can do in this window.

Build the foundations with food

Your body needs raw materials to build hormones, healthy follicles, and a receptive endometrium. Protein supplies the amino acids for hormone synthesis. Healthy fats -particularly omega-3s - support balanced oestrogen and progesterone production and oocyte membrane health. This is why very low-fat diets can backfire: they can reduce luteinising hormone and interfere with ovulation, which is the opposite of what you want right now.

Alongside this, folate, B12 and B6 support DNA methylation, ovulation and luteal-phase stability, while choline, zinc and magnesium support hormone receptor activity and the signalling involved in ovulation and implantation.

For women with irregular cycles or PCOS, myo-inositol is worth discussing too — there's good evidence it improves ovarian function, enhances insulin sensitivity, and supports more regular ovulation.

Look beyond the plate

Nutrition is one piece, but not the whole picture. Alcohol, smoking, and excess caffeine all affect hormone synthesis and egg quality, as do everyday endocrine disruptors like plastics and certain pesticides - worth being mindful of food packaging, cookware and skincare where you can.

Stress and over-exercising are the two I see most overlooked. Chronic stress competes with your reproductive hormones for priority in the body, and it can affect thyroid function too. Similarly, intense exercise paired with under-fuelling can lower luteinising hormone and disrupt ovulation - movement is good, but this isn't the window for punishing workouts on minimal fuel.

None of this needs to be perfect

The preconception period isn't about overhauling your entire life overnight. It's about giving your body - and your future baby - the best possible starting point, one little step at a time.

If you'd like support putting this into a plan tailored to you, I offer preconception consultations covering exactly this: testing, nutrition, and lifestyle, built around where you are right now.
