19 Weeks Pregnant

At week 19, your baby has had a bit of a growth spurt and is the size of a large mango.

Week 19 pregnancy

While your baby has had a bit of a growth spurt and is now about the size of a large mango, he or she has also developed vernix in week 19.

Nineteen Weeks Pregnant

Vernix caseosa has developed and now coats your baby’s skin. Vernix comes from the Latin word for varnish and caseosa means cheese. This description is fitting because it looks like waxy cheese that covers your baby’s body.

While it may sound a little strange, it is very important as it protects your baby’s skin from the amniotic fluid. Without the vernix, your baby’s skin would be very wrinkled at birth. Imagine what your skin would look like if you soaked in a bathtub for 9 months.

The vernix generally comes off as your baby is born but some babies have it on them at birth, especially babies that are born early or by c-section.

In addition to the vernix, your baby’s sensory development is taking off: smell, taste, vision, hearing and touch. Your baby can likely hear you read, sing, and talk, so don’t be shy, you are developing a relationship with your baby, even before he or she is born.

How You Are Changing

You may be experiencing a few different things right now. On the one hand, your libido is strong but on the other, you may be feeling round ligament pain. Many women find that their sex drive is high during the second trimester, due to raging hormones. However, as your belly begins to expand more rapidly, you may have achiness and even stabbing pain in your lower abdomen and sides, especially when you shift positions or have had a long day.

There are ligaments that support your uterus as it grows. As your belly increases in weight, these ligaments stretch and can cause discomfort. But this is a normal part of the process and there is nothing to be alarmed about.

Another change that begins to happen around 19 weeks of pregnancy is known as the “mask of pregnancy.” These are patches of skin that darken while pregnant but go away shortly after delivery. They may appear on your cheeks, forehead, or upper lip. In addition, your nipples, scars, freckles, underarms, inner thighs, and vulva may darken. A dark line from your belly button to your pubic bone may also appear, this is known as the linea nigra.
