Your baby's crown-to-rump length this week is approximately 12.8 inches and the total length is around 19.8 inches at this time. Your baby now weighs almost 5 pounds. From your bellybutton, it is about 5.6 inches to the top of your uterus. Measurements of your uterus vary from woman to woman. You should not worry if you do not measure the exact same as your pregnancy friends or family members as long as you are growing appropriately. When your uterus grows and gets larger at an appropriate rate, it shows that your baby is growing well inside of your uterus.
Braxton-Hicks contractions are going to get stronger and more frequent within the next few weeks. Braxton-Hicks contractions feel like a tightening at the top of your uterus that spreads down and then relaxes. Many women mistake Braxton-Hicks contractions for true labor contractions, but this is rarely the case. Braxton-Hicks contractions will diminish if you get up and walk around and they should not be painful.
Your baby's hair continues to get longer and thicker. Your baby's hair color probably is not going to be the same color from birth onwards, so you should expect it to change in color. Your baby is shedding most of lanugo, but the amount of vernix caseosa is increasing. Your baby is taking calcium from you to lay down lots of bone. Continue to take your prenatal vitamins and drink milk to ensure that you receive enough calcium.
If you were to deliver your baby now, it would probably be called a pre-term infant instead of premature. The only difference is in the maturity, particularly lung maturity. A pre-term baby is less likely to need intensive care because its lungs have developed. Doctors can test lung maturity with an amniocentesis that checks levels of surfactant.
The baby now rests on your uterus and is no longer floating.
Fingernails now reach over the finger tips and the baby can scratch itself.
