I was 11 weeks pregnant. The fetus at this time is approximately 3 in. long and about the size of a peach. The heart is beating, the brain is active, the genitals are visible, they respond to touch, and they move their fingers and toes.
Fertilization takes place. Genetic identity is complete including hair and eye color, gender, etc.
The heartbeat is detectable as early as 18 - 22 days by ultrasound. The following start to form: heart, brain and spinal cord, muscles, skeleton, and pancreas.
Blood circulation begins. Mouth opens. The following start to form: brain chambers, eyes, ears, arm buds, thyroid, vertebrae, spine, ribs, kidney, liver, and umbilical cord.
Embryo is the size of a BB pellet. Brain divides, pancreas begins producing insulin, body begins blood circulation, nerves extend into limb buds. The following start to form: leg buds, heart chambers, nostrils, appendix, intestines, eye lenses, and inner ear.
Embryo is the size of a pinto bean. The spine is clearly visible. The heart beats 150 times per minute. Brain waves are measurable. The following form: eyelids, nose, heart valves, fingers, blood cells, and joints. The embryo hiccups and has slow body movements.
Embryo is the size of a lima bean. The fingers, toes, elbows and knees are distinct. Internal organs are visible. Genitals are visible, skull bones are growing together and the immune system starts forming. Moves body, limbs, hands.
The size of a small plum. All organs are present. The central nervous system begins and the primitive skeletal system is complete. Joints complete and teeth buds form. The end of the embryonic period.
The unborn child is from this point until birth, called a fetus. Fetus is 2.4 inches from crown to rump. Brain activity in response to pain or noxious stimuli. Head position shifts. Kidneys produce urine and chest wall expands in early respiratory movements. Pupils form.
Bones harden, body hair forms, external genitalia visible. Digestive tract contractions and fetus produces hormones. Opens mouth, squints and moves fingers and toes. Extends arms and hands.
Fetus is 3 in. long and the size of a peach. Swallows and responds to touch. The body now grows faster than the head.
4 inches long. Gender can be distinguished. Body and organs are complete. Fetus grasps objects. Moves in jerks, flexes arms, and kicks.
Blood vessels visible. Slow eye movements visible via ultrasound. Brings hands together, sucks thumb, and moves arms and legs.
Fetus is 4.8 to 5.6 inches and about the size of an adult hand. Body fat begins to form under the skin. External ears stand out from head. Fetus actively turns inside the womb.
Fetus is 6 to 6.4 inches from crown to rump. Mouth and lips are formed. Eyes are closed but will move hands to block light. All important physiological systems have developed.
Fetus is 7.2 to 7.6 inches from crown to rump. Eyelids and eyebrows are complete. Fingernails are complete and reproductive organs are formed in girls.
Fetus is 8 to 8.4 inches from crown to rump and weighs 1 to 1.2 lbs. Body fat increases. Fetus can be startled by sound.
Fetus is 8.8 to 9.2 inches and can weigh up to 2 lbs. Can possibly survive born at 23 weeks and has a 50% chance of survival if born at 24 weeks.
