Fetal Development

Late in the third trimester

It's where it becomes relatively easier to save a baby. Deliveries Before 28 weeks have a much higher rate of Mortality & Complications due to Severe Prematurity.

hi, Im five months pregnant and only started to feel the baby kick in the lower abdomen about 18 - 19 weeks into pregnancy, it feels like gas bubble popping in the lower part of your stomach, it all depends on you everyones different, dont worry it just happens later for some people, hope this helped xxxx

Babies come out of a mommy's tummy through a C-Section.... Also known as a Cesarean Section which is a surgical procedure in which one or more incisions are made through a mother's stomach and uterus to deliver the baby.

Could possibly have to do with constricting of the umbilical cord if the mother is 30 to 40 weeks into the pregnancy.

Oxygen, Nitrogen, Carbon dioxide, Nutritions and alcohol can pass.

And only one type of antibodies can pass which is the IgG. Viruses can pass like HIV and HBV (Hepatitis B virus) that's why the affected mothers usually have affected babies.

When it dies.

The term womb drop actually is inaccurate. What actually happens is the baby drops further down in the womb. His head becomes engaged in the pelvis which means his head is pressing against the cervix, or the doctor/midwife will say the head is applied against the cervix.

In a first pregnancy this can happen a couple weeks before the baby is due. But it is exciting. it means everything is working and the time is getting close.

A woman who has already had a baby, sometimes doesn't "drop" until right around the time she goes into labor, or is in labor.

The above answer is actually incorrect, Yes you can tell the sex from 12 weeks onwards if the sonographer has researched and knows how to use the nub theory which is basically the angle of the dangle, every baby has a nub that does look like a willy up until around the 16th week but it is the angle of the nub which allows you to determine gender for boys the nub has to be pointing up on more than a 30 degree angle and girls lower, the girls nub tends to be flat and in line with the spine there is lots of information on the 'nub theory' which claims to be 95% accurate at 12/13 weeks and in my own personal experience having two little girls and seeing there nubs both me and sonographer agreed they were girls hope this helps :)

The placenta is the organ that feeds and shelters the fetus during pregnancy. It facilitates the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus through the maternal blood supply. Additionally, the amniotic sac, filled with amniotic fluid, provides a protective cushioning environment for the fetus, allowing for movement and development.

Average what? Weight? Length? Amount they eat? Please be more specific in your question.

Sometimes the baby turns and causes you not to be able to hear the heartbeat.

I am also 31 weeks. Congratulations! Our lamaze coach says that we should feel baby move at least 8 times in an hour. I don't really feel that unless I am lying down! So most of the day, when I am moving around I don't feel him much at all. Some days I feel him more than other days. I try not to panic when I don't feel him for a while. I lie down on my left side and try to relax and within a few minutes - I feel him bumping around. Good Luck!

Baby's heart can be seen beating when you do the first ultrasound scan at one and half month of missed period. It probably start beating at the age of five weeks of your last menstrual period. Initially it is a small tube gradually getting converted into heart by three months.

In the embryo the neural tube forms the central nervous system in the fetus, which is the brain and spinal cord.

The reason pregnant women are given folic acid supplementation is to help prevent neural tube defects, which can range from fairly benign all the way to anencephaly (where the baby is born without a brain).

around 27 weeks

First as the mother you must be taking your prenatal vitamins and eating properly. Which means when your thirsty you should drink, hungry you should eat or snack. Eating is what keeps your baby growing and eating is very important. Keeping iron up and drinking lots of fluids. If you have been doing all of these things then it is meant for you to have a smaller then average baby, if not at this point you are going to have him/her soon so just take the best care of your child once they are here. You can only do so much as a person so just take care of yourself eat right and do what you can.

The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta.

APEX~ a few days after fertilization

it isn't an exact answer it depends on the vagina.
