Week 15 of Pregnancy

Baby Size Comparison in Week 15

In week 15 of pregnancy your baby measures about 10 cm long and weighs about 70 grams: roughly the size of Apple. Remember these are approximate averages from standard growth charts; every baby grows at their own pace, and your doctor follows your baby's personal growth curve across visits, not a single number. If an ultrasound measures a little bigger or smaller than average, that is usually normal as long as growth continues at a steady rate.

Baby Development in Week 15

Taste buds form on the baby's tongue and it can distinguish strong flavors from what you eat through the amniotic fluid; garlic and hot spices really do reach it. The legs have become longer than the arms, and all the joints work so the fetus can move all its limbs.

The fetus senses bright light directed at the belly and moves away from it, and practice breathing movements begin by moving the chest muscles. Hair follicles have begun forming in the scalp, and the skeleton hardens. The skin is still thin and transparent, but a thin fatty layer has begun forming under it. The heart pumps about 25 liters of blood daily through the tiny body.

Your Body Changes in Week 15

Nosebleeds and congestion continue (pregnancy rhinitis) and may cause nighttime snoring. Glowing skin and thick, shiny hair are among the beauties of the second trimester from increased blood flow and hormones.

You may feel lower back pain as the belly protrudes and the center of gravity shifts; watch your sitting and standing posture. Forgetfulness and scattered focus (pregnancy brain fog) are real and common. Appetite is open and weight increases at about half a kilogram per week. Some women begin feeling a very light flutter like bubbles; it may be the baby's first movements, especially in a second pregnancy.

Light nosebleeds are normal; moisturize your nose with saline solution. Night leg cramps are eased by stretching before bed. Temporary forgetfulness is real; write down your appointments and tasks. And drink milk daily; calcium needs double now.
