Pregnancy Week 14 – The Baby’s Progress

By pregnancy week 14 your baby’s fetal heart beats are now pumping around 25 quarts of blood a day, this will increase to around 300 by birth. One quart equates to a quarter of a gallon, 2 pints or 4 cupfuls, so 25 of those is an awful lot of blood being pumped around something that is still not much bigger than an orange. It puts into perspective just how quickly your baby is growing and developing. Although your baby is beginning to establish sleep cycles you are not likely to be in tune with this yet until much later on in the trimester.

Pregnancy Week 14

As the bone structures in her body continue to harden this will add further definition to her appearance, for example, the bridge of her nose will appear, creating further profile to her face. The jawline will also develop now, defining her chin, and her head is now taking on a much more natural look. As the eyes continue to move a little closer together, the first signs of faint eyebrows will be appearing. She will also begin exercising the facial muscles, around pregnancy week 14, by pulling a variety of expressions from smiling, grimacing, squinting and frowning (aww!).

Now that the master pituitary gland has been created, which provides growth and other hormones that regulate the working of other glands in the body, the thyroid gland will have now begin to produce hormones. This gland is predominantly responsible for the metabolism of the body, growth and how fast we burn energy.

The neck, which houses the thyroid that is sometimes referred to as the ‘Adam’s Apple’ later in life, will now lengthen this week. In the male child, the ‘Adams Apple’ will protrude much further out on the neck, this is because when the male child reaches puberty the Larynx (which holds the vocal chords) will grow larger as the voice deepens, therefore pushing the ‘Adams Apple’ outwards (much like the female belly button does during pregnancy).

During pregnancy week 14, the ovaries of the females will drop down into the pelvis and the prostate gland will appear in the males. The female foetus will now have a full egg count in her ovaries of around 4 million eggs and this number will begin to decline rapidly throughout her life from this point on.

By the pregnancy at 14 weeks phase the male child’s testosterone levels will begin to peak for the next 4-5 weeks which will affect the growth of his sexual organs and that of his brain too. Scientists have determined that they are now able to tell the difference between the male and female brain at this very early stage in the womb.

She will now be approximately 3.5″ (8.9 cm) in length and will weigh around 1.5 oz (43 g) and can still fit into the palm of your hand like a peach. Imagine something that small being able to pull a face at you !
