About me

Knowledge, attentiveness and conversation.

I chose to become a doctor because I have always been fascinated by how a new human being comes into existence from the love of two people. I know, however, that the road to motherhood is not always free of difficulties. I wanted to understand the causes of failure and to help women who long to have a child.

Most often I see patients with complicated pregnancies, diabetes or hypertension, as well as women who have difficulty getting pregnant or carrying a pregnancy to term.

In my work I draw on knowledge gained over years of practice and through training in Poland and abroad. I turn it into practical steps for each specific problem.

After my care, my patients feel, above all, safe.

Pregnancy · 10 June 2026 The first ultrasound in pregnancy — what to expect When the first scan is done, what it looks like and what the doctor assesses.

When the first ultrasound is done

An early ultrasound is usually done between the 6th and 9th week of pregnancy. It confirms the pregnancy, its location in the uterus and the embryo's heartbeat.

The 1st trimester scan — the first of the prenatal tests — is done between 11+0 and 13+6 weeks of pregnancy. We set the exact date individually at the first visit.

How the scan is done

The scan is non-invasive and painless. In early pregnancy a transvaginal probe is usually used because it gives a clearer image. In later weeks the scan is done with a probe on the abdomen. It usually takes from about 15 to 40 minutes.

What the doctor assesses

  • whether the pregnancy is developing in the uterus — this makes it possible to rule out an ectopic pregnancy,
  • the number of embryos,
  • the heartbeat,
  • gestational age — based on measurements,
  • in the 1st trimester scan also nuchal translucency (NT), as part of the risk assessment.

How to prepare

Usually no special preparation is needed. Bring your medical records, remember the date of your last period and wear comfortable clothes. If you experience pain or bleeding, contact a doctor — do not wait for your scheduled visit.

The first ultrasound is not only a moving moment, but above all an important part of pregnancy care.

Diagnostics · 22 May 2026 3D/4D ultrasound — when is it worth doing How 3D imaging differs from a standard ultrasound and what affects image quality.

How 3D/4D ultrasound differs from 2D

A standard 2D ultrasound is the basic examination — the assessment of the baby's anatomy and development is based on it. A 3D ultrasound gives a three-dimensional image, for example of the baby's face. A 4D ultrasound adds movement seen live. 3D/4D scans complement standard examinations but do not replace them.

When it is best to do it

The best images of the face are usually obtained between the 26th and 30th week of pregnancy. Earlier, the facial features are less visible; later, the baby has less room in the uterus. It is best to agree on the timing with your doctor.

What affects image quality

  • the baby's position and activity during the scan,
  • the amount of amniotic fluid around the face,
  • the position of the placenta,
  • individual scanning conditions.

The first shot is not always perfect — sometimes the baby needs a moment to change position.

How to prepare

Staying well hydrated in the days before the scan and choosing a time of day when the baby is usually active often improve image quality. You will receive detailed advice when booking your visit.

A 3D/4D ultrasound is a keepsake and an additional look at your baby. Standard ultrasound scans at the recommended times remain the basis of a safe pregnancy.

Prevention · 15 April 2026 Pap test and prevention — how often to get checked What a Pap test involves, how to prepare for it and why regular check-ups matter.

A Pap test is an important part of prevention. It makes it possible to detect changes early — before any symptoms appear.

What a Pap test is

The doctor collects cells from the cervix, which are then examined under a microscope. The test is quick and causes little discomfort. Conventional cytology, liquid-based cytology (LBC) and HPV testing are used. The doctor chooses the method.

How often to get checked

It depends on your age, previous results and individual risk factors. Screening tests are repeated regularly, and we set the exact schedule during the visit. If worrying symptoms appear, do not wait for your routine appointment.

How to prepare

  • the test is done outside your period, ideally a few days after it ends,
  • for 1–2 days before the test, avoid sexual intercourse and do not use vaginal pessaries,
  • tell the doctor about the medicines you take and your previous results.

Prevention is more than a Pap test

Full prevention also includes regular check-ups, gynecological ultrasound and breast examination. In the appropriate age groups, HPV vaccination is worth considering. Regularity is what matters most.

If you cannot remember when you last had a Pap test, this is a good moment to book a visit.

The articles are for educational purposes and do not replace a medical consultation. The timing and scope of tests are set individually by the doctor.
