I am about 7 weeks and due around March 9th. The baby's heart has been beating since week 3. Its crazy to think that there has been a little heart beating inside me for 4 weeks and I didn't even know it! Here is where baby Honse is at:
SIZE: 13.0 - 18.0 mm
TIME PERIOD: 48 - 51 days post-ovulation
Head and Neck
The head is more erect and semicircular canals start to
form in the inner ear which will enable a sense of balance and body position.
Thorax
Septum primum fuses with septum intermedium in the heart.
Pelvis
The gonads form. In about a week, the sex of the
embryo will be recognizable in the form of testes on a male.
Limbs
Knee and ankles locations indicated by indentations.
Legs are now at their proper location, proportional to the embryo.
The critical period for the lower limbs is about to end.
Toes are almost completely notched and toenails begin to appear.
Joints grow more distinct.
Spine
The trunk elongates and straightens and the bone
cartilage begins to form a more solid structure. Muscles develop and get stronger.
