Pregnancy Care

Regular check-ups from the first positive test to delivery, with ultrasound and high-risk pregnancy monitoring.

When should I come for my first visit?

After a positive test, usually between weeks 6 and 8. This visit confirms where the pregnancy is and checks the heartbeat on ultrasound.

How often are check-ups?

In most pregnancies monthly until week 28, every two weeks until week 36, then weekly.

What is a high-risk pregnancy?

Pregnancies that need extra monitoring for mother or baby, such as older age, blood pressure, diabetes or twins. The plan is set per person.

Fertility and IVF

Thorough assessment for couples having trouble conceiving, plus IUI and IVF planning.

When should we come in?

If you haven’t conceived after a year of trying, or six months if you’re over 35.

What happens at the first visit?

We take your history, do an ultrasound and plan hormone tests and a semen analysis. Come together if you can.

What is the difference between IUI and IVF?

In IUI prepared sperm is placed in the womb. In IVF egg and sperm are joined in the lab and the embryo is transferred.

Book for this

Perimenopause and Menopause

Hormone assessment and treatment options for hot flushes, poor sleep and mood changes.

When does perimenopause start?

For most women in their 40s, a few years before menopause. Periods become irregular and hot flushes or poor sleep can start.

Is hormone therapy safe?

It depends on the person. We decide together after reviewing your personal and family history.

Are there non-hormonal options?

Yes. Lifestyle changes and non-hormonal medicines reduce symptoms for many women.

Book for this

Women’s Health

Annual check-ups, smear tests, irregular periods, cysts and fibroids.

How often should I have a smear test?

Usually every three to five years, depending on your results and age. It can be combined with an HPV test.

When do irregular periods need a visit?

If irregularity lasts over three months, or with very heavy or in-between bleeding.

Do cysts and fibroids always need surgery?

No. Most are monitored. Surgery depends on size, symptoms and your pregnancy plans.
