what is the baby doing at 5 weeks old during pregnancy?

Answer 1

How your baby's growing: Deep in your uterus your embryo is growing at a furious pace. At this point he's about the size of a sesame seed, and he looks more like a tiny tadpole than a human. He's now made up of three layers — the ectoderm, mesoderm, and endoderm — that will later form his organs and tissues. The cells are forming for his major organs, including his kidneys and liver, and his neural tube is beginning to develop. This neural tube — from which your baby's brain, spinal cord, nerves, and backbone will sprout — develops in the top layer, called the ectoderm. This layer will also give rise to his skin, hair, nails, mammary and sweat glands, and tooth enamel. His heart and circulatory system begin to form in the middle layer, or mesoderm. (This week, in fact, his tiny heart begins to divide into chambers and beat and pump blood.) The mesoderm will also form your baby's muscles, cartilage, bone, and subcutaneous (under skin) tissue. The third layer, or endoderm, will house his lungs, intestines, and rudimentary urinary system, as well as his thyroid, liver, and pancreas. In the meantime, the primitive placenta and umbilical cord, which deliver nourishment and oxygen to your baby, are already on the job.

Answer 2

You may not look pregnant at this point but your embryo's heart, no bigger than a poppyseed, has already begun to beat and pump blood. The heart is dividing into chambers and will find a more regular rhythm soon. The embryo itself is about a quarter of an inch/ half a centimetre long and looks more like a tadpole than a human. It undergoes a growth spurt this week.

Major organs, including the kidneys and liver, begin to grow. The neural tube, which connects the brain and spinal cord, will close this week. The embryo's upper and lower limb buds begin to sprout -- these will form your baby's arms and legs. The intestines are developing and the appendix is in place.

Below the opening that will later form your baby's mouth, small folds exist where the neck and the lower jaw eventually develop. As early as this week, facial features are already forming. Nostrils are becoming distinct and the earliest version of the eyes' retinas are forming. Find out how much folic acid you need.

They are very busy developing. The length of the embryo is about 1.5 to 2 millimeters long. All of your baby's major organs are under development, and facial features, such as ears and eyes, begin to form. The neural tube, which will later be referred to as the spinal cord, will fuse this week. And buds appear that will soon be the arms and legs.


Also, I used to have a book that is called "What to expect when you are expecting". You can get it just about anywhere and if you are pregnant I do suggest you get it. It takes you frmo month to month telling you what is going on with you and your baby. Good luck.

Your breasts may feel tender, rather like the tenderness you may have mid-cycle 'round about ovulation time.
Your nipples may look a little different from this time. You may be able to see tiny raised spots called Montgomery's tubercules on them, which will secrete an oily fluid to prepare your nipple skin for feeding.
The ovary which gave up its egg continues to produce progesterone. This works on the cells on the inside of the uterus to support the pregnancy. It builds up and thickens the lining, and stimulates its production of hormones.
If an earlier pregnancy test was negative, and you still feel you may be pregnant (no sign of your period, for example) then take another test, there may be more hormone present now in your urine for the test to detect.
The embryo is about two millimetres long. Tiny, but visible.
Your `fetus`, about 5 weeks old
On your initial doctors visit you may be checked on Hematocrit, hemoglobin, white blood cell count, blood group type, Rh factor, antibodies to blood group antigens, VDRL, rubella anti-Body titer, hepatitis B, toxoplasmosis, urine culture, and HIV.
Sometimes as early as the second month of pregnancy, the insides of your hands and the bottoms of your feet may itch and take on a reddish hue. This annoying condition is called palmar erythema. The increased color is nothing more than a curiosity of pregnancy.

Answer 5

This is a really exciting time, because at 5 to 6 weeks pregnant is when the baby's heart starts beating! Congratulations and good luck!

Answer 6

Week 5:
Eyes are starting to form, a mouth-like opening appears near the "head"; finger and toes are beginning to form. The brain now has three recognizable divisions, as it does in the fully-developed baby and adult.

you could try registering with one of the many baby clubs, they show you different stages as they become applicable to you.
