Understanding fertility and pre-conception health

Why pre-conception care matters

The weeks before you conceive are just as important as the pregnancy itself. Your health at the time of conception affects your fertility, your pregnancy, and your baby's development — particularly in those critical early weeks before you may even know you're pregnant.

Pre-conception care involves optimising your health, identifying any risk factors, starting the right supplements, and making sure your vaccinations are up to date.

What to do before trying

Start taking folic acid at least one month before trying to conceive — ideally three months. Your GP may recommend a higher dose if you have specific risk factors. They'll also check your immunity to rubella and chickenpox and arrange vaccinations if needed.

Your GP can arrange blood tests to check your iron, thyroid, and overall health, review any medications you're taking, and discuss lifestyle factors like diet, exercise, alcohol, and smoking.

When to seek help

If you've been trying for 12 months (or 6 months if you're over 35), it's worth speaking with your GP. They can arrange initial fertility investigations for you and your partner and refer you to a fertility specialist if needed.

Pre-conception care isn't just for women — male factors account for about half of fertility issues. Encourage your partner to have a check-up too.
