Pregnancy After IVF: What You Need to Know 

Pregnancy after IVF is, in the vast majority of cases, no different from a naturally conceived pregnancy. Once the embryo implants in the uterus, the body does not ​“recognise” how fertilisation occurred. Fetal development, pregnancy symptoms and the course of labour are practically the same. 

The slightly increased risks sometimes associated with IVF pregnancies (such as preterm birth or preeclampsia) are linked far more to maternal age or the underlying cause of infertility than to IVF itself.

The differences you may notice occur mainly in the early weeks, when follow‑up appointments at your fertility clinic are appropriate. About one month after the embryo transfer, your pregnancy is handed over to your regular obstetrician, who then monitors it just like any other naturally conceived pregnancy.

What Happens After a Positive Pregnancy Test?

About 14 days after your embryo transfer, you take a pregnancy test. If the result is positive, we confirm the pregnancy with a blood test — measuring beta‑hCG, which helps us understand whether the embryo is developing correctly.

Within the next two weeks, you will come in for a follow‑up ultrasound. This first scan usually takes place around week 4, when we confirm the fetal heartbeat and make sure everything is progressing as it should. Your subsequent check‑ups are then carried out by your obstetrician, who takes over your care from that point.

Hormonal Support in the First Trimester

Another difference in IVF pregnancies is the use of progesterone and occasionally other hormones to support the uterine lining. In naturally conceived pregnancies, the body produces these hormones on its own — but after IVF, we give your body a little help at the beginning.

These medications are typically taken until week 10 – 12, when the placenta takes over hormone production.

Fact: IVF itself is not an indication for a C‑section. The mode of birth depends on the mother’s current health and the baby’s position — exactly the same as in any other pregnancy. Many women after IVF give birth vaginally without any complications.

Slightly Increased Risks — and Why You Don’t Need to Be Afraid

Studies show that pregnancies after IVF may have a slightly higher likelihood of certain complications compared to spontaneous conception. These include, for example:

• Gestational diabetes — diabetes that appears during pregnancy. Incidence of gestational hypertension is around 0.9% higher, and gestational diabetes 2.2% more common in IVF pregnancies.
• Preeclampsia — a condition characterised by elevated blood pressure.
• Preterm birth — delivery before 37 weeks. The risk is about 1.7× higher.
• Low birth weight — about 1.5× more likely.

While these statistics can seem worrying at first glance, context is extremely important. Most of these risks are not caused by IVF, but by the same factors that led couples to seek fertility treatment in the first place — especially advanced maternal age and various underlying health issues.

A large Australian study found that once maternal age and health were taken into account, the difference in congenital anomaly rates between IVF and natural conception was virtually negligible.

Modern reproductive medicine additionally lowers these risks:

• clinics now usually transfer only one embryo, reducing the risk of multiple pregnancies — previously the main cause of IVF‑related complications,
• with preimplantation genetic testing (PGT), we can screen for chromosomal abnormalities before transfer.
  
  

As a result, the vast majority of children born after IVF are completely healthy. Global data confirm that their physical and cognitive development is equivalent to that of children conceived naturally. The baseline risk of congenital anomalies in the general population is 2 – 3%, and in IVF pregnancies it increases only slightly — by about one percentage point.

The Emotional Side — A Natural Part of This Stage

The physical aspects of pregnancy after IVF are often discussed, but the emotional side receives much less attention — even though emotions are often what most distinguish IVF mothers from others.

After months (and sometimes years) of treatment, unsuccessful attempts, and an emotional roller-coaster, the long‑awaited positive test finally arrives. But instead of pure, carefree joy, many women experience a paradoxical reaction — fear that the pregnancy might be lost. Experts refer to this as the ​“precious pregnancy syndrome”, and a significant number of women after IVF experience it. Every twinge in the lower abdomen, every day without morning sickness can trigger doubts about whether everything is still progressing as it should.

These feelings are completely normal. After such a difficult journey, it’s natural that it takes time to truly believe that this pregnancy is real and healthy. But it’s important not to let these worries take over. A few things may help:

• Talk openly about your feelings — with your partner, loved ones, or even a psychologist.
• Trust your doctor and avoid sinking too deep into online forums — the internet often frightens more than it helps.
• Focus on what you can control — a healthy diet, gentle activity, enough rest. These are the best things you can do for your baby.
• Allow yourself to enjoy the pregnancy — you deserve it, and a positive mindset contributes to a calmer and healthier experience.
