You will notice changes within your body now as your hair becomes fuller and healthier looking. Your nails will probably grow more rapidly than before and even harden some. Enjoy these rewards due to your hormonal changes. Once you have the baby your hair and nails will return to their usual state. You can still exercise during this time but use caution. Do not over exert yourself. When you are tired, take a break. Stay in tune with your body and what it is telling you.
The luster of your hair and length of your nails has greatly improved. Most women are said to carry that glow about them when they are pregnant and in this stage, it is more apparent. Your abdomen will continue expanding so do not be surprised if one week you can wear something and then the next it does not fit. This is all normal as your body accommodates your growing bundle of joy.
Your baby is rapidly growing and now weighs over a pound and a half and is measuring over 13 inches in length. Your baby's overall appearance is starting to resemble that of a newborn. Veins and capillaries under the skin are now formed and filling with blood. The air sacs within the lungs are developing in preparation of your baby's first breath. In addition, we cannot forget about the vocal chords. Right now, they are slowly maturing and becoming more ready to be heard once the baby is born.
At 25 weeks pregnant, you are more than likely feeling pregnant, aren't you? You definitely know your baby has done a lot of growing because you can now compare baby to the length of a bushel of grapes on a vine. And the baby will continue to grow more in the weeks to come.
