You are now 6 weeks pregnant (28 days after conception), which is the beginning of week 7. The woman's period is two weeks late. For many women, the physical signs of early pregnancy are now becoming quite noticeable. Your baby's crown to rump length is about 5 mm (or 0.2 of an inch) and their facial features are gradually building up around a wide mouth. Their lower jaw forms first, shortly followed by their upper jaw. Your baby's head and forehead are comparatively large and their brain is now forming within, with the start of bulging eyes on each side of their head. Some scientists have compared the look of unborn babies at this stage to that of E.T!
Your baby's limbs start to lengthen to form arms and then legs, with their hands and feet resembling ridged paddles, that will eventually become fingers and toes. Their internal organs are also taking shape. Their gullet (or 'oesophagus'), stomach, kidneys and bowel are being defined, as well as 2 small buds which will form into lungs. Their heart is forming chambers and is beating away efficiently at 120 to 180 beats per minute! An ultrasound at this stage can detect an unborn baby's heart beat relatively easily, unless the pregnancy is less advanced than first thought.
