What Does My Baby Look Like at 6 Weeks?

Six weeks pregnant. You may have only just seen those two lines on the test — and yet inside, something remarkable is already happening. Your baby is tiny, but the foundations of an entire human being are already being laid at an astonishing speed. Here is exactly what your baby looks like at 6 weeks, what is developing right now, and what you would see if you booked an early pregnancy scan in Camberley or the surrounding Surrey area today.

How Big Is My Baby at 6 Weeks?

At 6 weeks, your baby — known at this stage as an embryo — measures approximately 4 to 6mm from crown to rump. That is roughly the size of a sweet pea or a pomegranate seed. Incredibly small, but already changing every single day.

What Does a Baby Look Like at 6 Weeks?

At 6 weeks the embryo does not yet look like a baby in the way you might picture. The head is disproportionately large, and the body is curved in a C-shape. Small buds are beginning to appear where the arms and legs will grow. There is a small tail-like structure which will disappear over the coming weeks. The face is beginning to take shape — dark spots mark where the eyes will be, and small indentations show where the ears and nostrils are forming. It is primitive, but it is unmistakably the beginning of your baby.

What Is Developing at 6 Weeks?

Week 6 is one of the most critical weeks of development. Here is what is happening right now:

• The heart — this is the most significant development at 6 weeks. The heart is now beating — typically between 90 and 110 beats per minute at this stage, rising to around 150 to 170 bpm over the coming weeks. It is one of the first organs to function

• The neural tube — closing this week to form the brain and spinal cord. This is why folic acid in early pregnancy is so important

• Limb buds — tiny arm and leg buds are beginning to emerge from the sides of the body

• Eyes and ears — the optic vesicles that will become the eyes are forming, and the inner ear structures are beginning to develop

• The digestive system — the stomach and intestines are beginning to take shape

• The placenta and umbilical cord — developing rapidly to take over the job of providing nutrients and oxygen to the embryo

Can You See a Heartbeat at 6 Weeks?

Yes — in most cases. A heartbeat can typically be detected by transvaginal ultrasound from around 6 weeks, though it depends on the exact gestational age and the position of the embryo. At 6 weeks exactly, the heartbeat may be very faint or not yet visible. By 6 weeks and 3 to 5 days, it is usually clearly detectable. If a heartbeat is not seen at 6 weeks, a repeat scan a week or two later is usually recommended before drawing any conclusions.

What Would I See at a 6-Week Scan in Surrey?

At our private clinic in Camberley, Surrey, we offer early pregnancy scans from 6 weeks for families across Surrey, Hampshire, and Berkshire — including Farnborough, Fleet, Aldershot, Woking, Guildford, Bracknell, and Wokingham. At a 6-week scan you would typically see:

• A gestational sac — the fluid-filled sac surrounding the embryo, visible from around 4 to 5 weeks

• A yolk sac — providing nutrients to the embryo before the placenta takes over

• The embryo itself — a tiny curved shape measuring 4 to 6mm

• A flickering heartbeat — one of the most emotional and reassuring moments of early pregnancy

• Confirmation that the pregnancy is in the uterus and not ectopic

A 6-week scan is almost always performed transvaginally for the clearest image, as the embryo is still very small and low in the pelvis. Your sonographer will explain everything they can see in real time.

What Symptoms Might I Have at 6 Weeks?

At 6 weeks, pregnancy symptoms are often just beginning to ramp up as hCG levels rise rapidly. Common symptoms include nausea (with or without vomiting), sore or tender breasts, extreme tiredness, needing to urinate more frequently, a heightened sense of smell, food aversions, and bloating. Some women feel barely any symptoms at all at 6 weeks — this is equally normal and does not indicate a problem.
