At pregnancy week 27, your little one is 14.4" long and 1.9 pounds in weight. Now your baby has all the proportions of a newly-born baby, but will still grow and fill out till delivery. All the different systems are developing, growing and maturing. Your little one's skin is still wrinkled like a prune, because of the amniotic fluid that surrounds.
It is in pregnancy week 27 that the light sensitive part of the eyes that is the retina, begins to mature. The retina is the part of the eye which has cells called rods and cones, which can receive light stimuli from the objects outside, and send impulses to the brain, which translates it into images. This is how the eyes see. Even after birth the sight would not be effective as it is still developing and maturing. For many weeks, the eyelids were fused tight, but in a week or two will open.
How are you doing in pregnancy week 27? Your uterus continues to grow and the fundus is now nearly 2.8" above the navel. This is the end of the second trimester, and you are going into the third trimester. The energy that you had in the second trimester is fast disappearing, as you are about to go into the third trimester. As your baby in your uterus is developing, growing and maturing; more energy is used to keep up with the growing fetus, such as for the extra demands on your circulatory system. So you are using a lot of energy, and as a result you feel tired and fatigued. Rest during the day as often as you can, by taking short naps. You'll get up more energetic and refreshed.
Some pregnant women may have an increase in false labor or Braxton Hicks contractions, from now till later. These contractions are nothing to be worried about, unless you have a history of premature labor. You still may have the other symptoms of pregnancy such as water retention; abdominal cramps; aches and pains; and headaches.
If you have some of these symptoms, such as a spurt of clear watery liquid from the vagina; red blood staining; more than 5 contractions in one hour, swelling of face and hands and intense pelvic pain; you must call your doctor immediately.
As you have grown big you may experience breathlessness. This is because the uterus is pressing up towards the lungs, and your lungs find it difficult to expand. But that does not matter; you still have enough oxygen for yourself and your little one. Your body needs slightly more than 300 calories daily. As you continue to put on weight, keep on eating good healthy, high fiber foods, and drink a lot of pure water.
