Your Baby at 10 Weeks

A Closer Look at Week 10

Week 10 is a major milestone in your baby's organ development. By now, all of the vital organs — the kidneys, intestines, brain, and liver — are not only in place but are beginning to function. The liver is producing bile, the kidneys are filtering blood and producing small amounts of urine, and the brain is generating an astounding 250,000 new neurons every minute. Your baby is now the size of a strawberry.

One of the most endearing developments this week is the appearance of tiny fingernails and toenails. The webbing between the fingers has fully dissolved, and each digit is now distinct and separate. Your baby's joints — elbows, wrists, knees, and ankles — are all working, allowing for more complex movements. Though still too small to feel, your baby is now actively kicking, stretching, and even hiccupping inside the amniotic sac.

You may notice that your veins are becoming more visible, particularly on your breasts, abdomen, and legs. This is completely normal and is caused by the significant increase in blood volume that occurs during pregnancy — by the end, your body will contain nearly 50% more blood than before conception. Constipation is another common symptom at this stage, driven by progesterone slowing your digestive system. Increasing your fibre intake through fruits, vegetables, and whole grains can help, along with staying well hydrated.

Your waistline may be starting to thicken, even if a visible bump hasn't appeared yet. This is a good time to invest in a few pieces of maternity clothing or simply switch to looser, more comfortable garments. A belly band can extend the life of your regular jeans by covering the unbuttoned waistband.
