Fetal Development

embryo

The first three months of pregnancy are the first trimester

It is so the baby's head can fit through the mother when its ready to deliever. It's nothing to do with not eating the right amount of food.

Late in the third semester

You do what is best for your child and yourself - you have to keep going for the two of you and above all for your child. Join some mother & child groups and spend time doing things that keep you busy and happy, not only will you meet new people within the groups you will be spending time with your child and occupying your time which you will realize heals all wounds. It will just take some time and it will get better.

Never. Through out the entire pregnancy the fetus is in a sleep like state and can not feel pain until week 28-30.

It's not illegal to find out the sex of your baby but in some countries it's illegal to have an abortion based on the gender of the baby. Discrimination because of the sex is illegal in many countries.

It appears after 22 days of pregnancy. It comes from primary yolk sac. Primary yolk sac gets enclosed inside from folding of the fetus, the rest is secondary yolk sac, which goes down to mesoderm and shrinks.

Yes it can, but you have to continue this diet for a month or so. Best thing is to avoid too much protein.

It depends. My baby died at 8 weeks and I found out at 12 weeks through an ultrasound, and it was removed by D&C

It can if there is an unusual amount in the mother's environment. Anything that is in the blood of the mother is sent through the foetus, and anything discarded by the foetus is sent through the mother's bloodstream.

Embryos are genotypically a boy or a girl at the time of conception. The chromosomes they inherit make them either XX(girl) or XY(boy). Because a female is XX, she will always contribute an X chromosome, but because a male has both, X and Y (XY), the male could either contribute an X chromosome or a Y chromosome.

From the first time the hearbeat is heard/seen it will be between 120 and 160.

Hi... my friend went through this previously. She took a home pregnancy test, it was positive. When she went in for an ultrasound, they said there was no baby in there, only a sac. She thought that they were crazy, so she got a 2nd opinion...same thing. The doctor told her it would pass naturally. But beware... when she called me and she was passing it, I rushed to her house and she was completely incoherent and had lost way too much blood. I called an ambulance and they took her in for surgery. All I can say, is while yes it is weird it is also possible, but please make sure you call someone if you suspect something unusual. This is a fairly common finding before a miscarriage. The embryo does not develop so the placenta is miscarried.

Yes it can do that because the uterus is growing to accommodate the fetus. Depends on what kind of pain though. if you are worried contact your doctor.

A fetus does not eat through the digestive system, so there is nothing to turn into feces. The umbilical cord feeds the fetus, provides oxygen, and removes wastes. Therefore, the fetus doesn't have to eat or breathe on its own.

The fetal circulation is based mainly on the veinous circulation during pregnancy. Once the uterine connections are lost, the adult circulation takes over.

The embryo or fetus is contained in a sac filled with amniotic fluid, commonly referred to as the bag of water.

It will be born with a sensory defect such as blindness, deafness etc.

you cant choose whether you want a boy or girl it just comes :)

It will be too full of wastes that may be harmful (ex. e. coli) and will not be able to absorb essential nutrients. It's tissues may burst and the whole organism may malfunction. It's just like hoarding. The more stuff you have, the less room there is in your house for the stuff you need. In organisms, the more wastes remaining in the body doesn't allow the body to function properly and have enough of the essentials.

One reason I learnd is that your sugar level may have dropped at night causing your baby to move.

The most rational answer so far that I understood is during at night, when you tend to lay down and rest, your body is not making any movements to craddle your little one thus, this made him awake.

No. It could indicate that the child has a birth defect of some sort, since if one abnormality exists, others are quite possible. It does not mean that the child has any specific birth defect, or even that the child has one.

The placenta and umbilical cord is the structure responsible for the fetus receiving nutrients from its mother.
