Week 8 of Pregnancy

Baby Size Comparison in Week 8

In week 8 of pregnancy your baby measures about 1.6 cm long and weighs about 1 gram: roughly the size of Olive. 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 8

The week of joints and fingers: the fingers and toes begin forming, though still joined by a thin web that will disappear later, and the elbows and knees take shape so the embryo can bend its limbs with spontaneous movements. The first kidney works and begins producing urine, and the embryo grows eyelids that cover the eyes.

The outer and inner ear develop, the tip of the nose stands out, and the upper lip takes shape. The lungs begin as small buds that will branch later. By the end of this week, the embryonic stage (embryo) ends and the fetal stage (fetus) begins; all the essential organs have formed and will now start growing and maturing. The embryonic tail nearly disappears.

By the end of this week, the embryonic period ends and the fetal period begins; all the essential organs have formed and will enter the stage of growth and maturation. The fingers form, though still joined by a thin web that will fade gradually, and the elbows take shape so the embryo bends its arms. The first kidney works and begins producing urine, and the eyelids form. The tail-like appendage nearly disappears and the shape becomes clearly human. From now on, the risk of major birth defects drops because the essential organ-formation stage has ended safely.

Your Body Changes in Week 8

The uterus is the size of a large orange and you may feel fullness in the lower abdomen. Nausea is still at its peak for most, and exhaustion makes the simplest tasks tiring. The sharp sense of smell and aversion to once-loved foods are daily matters.

You may notice increased saliva or mild heartburn, and sharp mood swings between joy and tears for no reason. The breasts keep growing and you may need a larger bra size. Constipation, bloating, and gas are common from slow digestion. Remember: this peak is temporary; most women begin improving after week twelve.

At the first visit, the doctor will measure your blood pressure and weight and order comprehensive tests: blood type, hemoglobin, sugar, and immunity. Prepare your health history, your period history, and any medications. Do not hesitate to ask the doctor about everything that worries you; there is no silly question in pregnancy. And ask for the clinic's emergency number.

Practical Tips for Week 8

• Book your first visit with an obstetrician between weeks eight and ten if you have not already.
• Prepare a list of your questions, medications, and health conditions to discuss at the first visit.
• Wear comfortable clothes and a supportive bra; the breasts are growing and becoming more sensitive.
• Eat fiber (vegetables, fruits, oats) with water to ease constipation and bloating.
