Fetal Development

Yes EVERYBODY has different DNA even if you are identical twins.

The growing baby has wastes and needs oxygen and nutirnets through out its time in the womb... The placenta holds many tiny cappilaries( very small blood vessels) Half are babies, and half are moms. These blood vessels run very close to each other.. The oxygen and nutrients that the baby needs are diffused from the mothers cappilaries to the babys cappilaries. In other words the oxygen and nutrients in the mothers blood is passed to the babys blood with out touching, the tiny particles are small enough to go through the walls of the cappilaries. These much needed nutrients are then taken to the baby through the imbilical cord.

The baby also makes many waste products, carbon dioxide, urea(what makes up most of urine), extreme amounts of water, and salt are a few.. These waste go through the imbilical cord, to the babies tiny cappilaries in the placenta. Then it diffuses into the mothers cappilaries in the placenta.. The mother then gets rid of these waste products.

women have hystertomies because they are having problems with fibroids( large benign bleeding tumours) that cause discomfort and pain, if they are not removed they can become cancerous.

NO WAY! At one week the baby is way too tiny to be felt...people can barely detect that there is a baby at this stage. I'm 7 months pregnant and didn't feel the baby kick until 6 months into it. I heard if you're REALLY skinny you might feel it at 3-4 months, but that's in special circumstances.

Fingerprints are developed by 17 weeks in the womb.

Air sacks are developing in your baby's lungs, which means it just might be possible for your baby to take a breath at the end of this week. The air sacks will continue to grow for the next nine years.

This week the retina will also by completely developed, although his or her eyes are still sealed shut .

Your baby's brain is starting to register things like light and sound, although it doesn't make sense to him/her yet.

As hearing continues to develop, your baby will start to recognize your voice and even your partner's voice! Research has shown that newborns actually recognize familiar sounds after birth.

Your baby is about 1 2/3 pounds and is 14 inches long!

Different people show at different rates. Just because your belly has not grown at 14 weeks doesn't mean that your baby is not alive. Can you feel your uterus growing above your pubic bone?

You should see a doctor, who can use a Doppler to detect a heartbeat at this point. He can also order an ultrasound to check on things.

Answers to this questions are unfortunately going to be more opinion then actual answers. Because, let's face it, not everyone believes the same things. Some believe that as soon as the two "parts" come together at the moment of conception, that the resulting genetic material has a soul. Others believe that there is no such thing as a soul. Most people though believe something between the two. I myself believe that most people earn their souls by age 5. (Yes, I believe that we earn our souls through good deeds).

The only definitive answer I can really give you is to say that in several places the Bible mentions life (and the soul) as breathing. No breath no life. Ex. Genesis 2:7 "and breathed into his nostrils the breath of life, and man became a living soul". Other references are Ezekiel 37:10, I Kings 17:17-21, and James 2:26. Since a fetus doesn't breathe it doesn't have a soul, according to biblical definition.

And the pope himself (I believe in the 1600's) said that a fetus is not a person until 120 days (18 weeks/4 months).

Hope this helps at least a little.

If it is your first baby this is about what you would expect, the baby will come when it is ready. 2/6/2008: I'm sure since you have already had 2 children that you are aware of what your body is telling you and are just anxious about the baby coming "early"... perhaps you are looking for some reassurance from other mothers, but be assured that anytime after 36 weeks, the baby could come and the important parts of baby's development are completed... but also know that your body can begin readying for baby's arrival WEEKS in advance of the actual birth date! I began dialating, softening and effacing at least three weeks before my son actually arrived! He ended up being 5 days late! You just don't know what will happen! That's why they call it "the miracle of birth"! Even your due date is really just a "guess" the doctor makes because the conception process is so mysterious and hard to pinpoint. Like the previous poster said, "baby will come when it is ready". That's so true! But be prepared that you may still have weeks ahead of you of waiting!

Lanugo

Because humans do not need them fully developed to survive. Notice the size of the head and torso. Early development is focused on the brain and other organs. A parent will care for the baby until the legs are strong.

6 week pregnant but no but cant see heart beat. what does this mean and is it to early to see ?

At 17 weeks your baby is practicing sucking his thumb and swallowing this week! The fingernails and toenails beds are developing this week too!

At 17 weeks, the baby is roughly 11cm long. See the related link for a picture and more details

A chick's heart starts to beat 3 days after incubation has begun (an unincubated, fertilized egg remains viable many days after it is laid...the hen only starts warming them after she has laid a "clutch", or set (usually 6-8.)

If the baby is healthy, it should Be growing right up until you give birth.

The death of an embryo or fetus in the first 20 weeks of pregnancy is called a spontaneous abortion.

No, sometimes doctors get the dates wrong or sometimes the baby is a little ahead or behind in growth. I would go by the Ultrasound.

Examples will vary. The advantage of inbreeding is that it maintains desired traits within a breed, such as curly hair in poodles. The disadvantage is that it can lead to genetic defects within a breed, such as blindness in German shepherds.

Faster than what? Elephant pregnancies last for approximately 22 months.

No, twins are a result of genetic flukes or hyperovulation or artificial means. Hyperovulation is a condition that causes the mother to produce more than 1 egg at a time. Orgasm has nothing to do with how many babies you get and most mothers can expect 1 baby per pregnancy.

The fetus gets all the oxygen he needs from the mother's blood by way of the umbilical cord. After birth, he must take his first breath and he will cry at the same time. This crying causes him to take in more air. The lungs will begin to work just as they do now in you.

no all the organs are not completely formed until week 13.

No. And it's not good either for the baby. And be proud of the showingness because a baby is a precious gift.

It depends on how old the baby is. If it's unborn or a newborn then no, that is uncommon and I would consult your doctor. An unborn or newborn's heart rate should be between 130 - 150 bpm with some variability, depending on how far along in development it is.

Also, it depends on how you got the number 72. If you were measuring the bpm yourself it is extremely likely that you picked up your heart rate and not the baby's. This can even happen in doctor's appointments but the doctor will notice and adjust the ultrasound monitor to pick up the baby's heartbeat.
