BEETLE : A LEGEND ON WHEELS

One o f Hitler’s dreams was to increase the number of car owners in Germany, so he employed Dr. Ferdinand Potsche, the well-known construe lOr, to design an affordable and reliable car for the people. Hitler and “Potsche often had arguments, but Potsche was afraid of him, so he stayed in the project and continued his work in the Waifs burg car factory. In 1938, the factory produced the first cheap car “for the people”. It included all the characteristics that Hitler ordered. The engine was at the back of the car and it had quite a specific shape: Continue Reading “Beetle”

GOING FOR GOLD

 

Gold was probably first found on the ground and used by prehistoric man in tool-making. In ancient times, it was made into plates, cups, vases and vessels of all kinds, and of course, jewelry. The first use of gold as money occurred in Anatolia in 670 BC, but it has always been accepted as money anywhere in the world. Sailors, for example, wore a gold earring.

MIRRORS

 Mirrors have always been considered as having special powers. The superstition that breaking
a mirror is bad luck is very, very old. This belief can be observed in some form in most
cultures around the world, but, in fact, the first mirrors could not really be broken because
they were made of water. People looked at themselves in lakes, ponds and rivers because they
believed that by looking at their reflection in the water they could learn about their future.

Calculating Conception

Calculating Conception

Gestational age, or the age of the baby, is calculated from the first day of the mother’s last menstrual period. Since the exact date of conception is almost never known, the first day of the last menstrual period is used to measure how old the baby is.

Use our Pregnancy Calculator to calculate these dates for you.

Calculating Gestational Age

Last Menstrual Period

If the mother has a regular period and knows the first day of her last menstrual period, gestational age can be calculated from this date. Gestational age is calculated from the first day of the mother’s last menstrual period and not from the date of conception.

Ultrasound

 The baby can be measured as early as 5 or 6 weeks after the mother’s last menstrual period. Measuring the baby using ultrasound is most accurate in early pregnancy. It becomes less accurate later in pregnancy. The best time to estimate gestational age using ultrasound is between the 8th and 18th weeks of pregnancy. The most accurate way to determine gestational age is using the first day of the woman’s last menstrual period and confirming this gestational age with the measurement from an ultrasound exam.

Calculating Conception Date

In a Typical Pregnancy

For a woman with a regular period, conception typically occurs about 11-21 days after the first day of the last period. Most women do not know the exact date of conception because it can be challenging to know exactly when ovulation occurs. Thus, their conception date is merely an estimate based on the first day of their last period.

Special Cases

Women who undergo special procedures, such as artificial insemination or in vitro fertilization, typically know the exact date of conception.

Calculating Due Date:

Estimated Due Date

Based on the last menstrual period, the estimated due date is 40 weeks from the first day of the period. This is just an estimate since only about 5% of babies are born on their estimated due date.

Difficulties In Determining Gestational Age

Last Menstrual Period

For women who have irregular menstrual periods or women who cannot remember the first day of their last menstrual period, it can be difficult to determine gestational age using this method. In these cases, an ultrasound exam is often required to determine gestational age.

Baby’s Growth

In some cases, it is difficult to determine the gestational age because the baby is unusually large or small. Also, in some cases the size of the uterus in early pregnancy or the height of the uterus in later pregnancy does not match the first day of the last menstrual period. In these cases as well, it is difficult to obtain an accurate gestational age.

The Fetal Life-Support System: Placenta, Umbilical Cord, & Amniotic Sac

 

Your baby will develop inside your uterus with the help of a fetal life-support system composed of the placenta, the umbilical cord, and the amniotic sac (which is filled with amniotic fluid).

What Is The Placenta And What Does It Do?

Human Chorionic Gonadotropin (HCG): The Pregnancy Hormone

The hormone human chorionic gonadotropin (better known as hCG) is produced during pregnancy.

It is made by cells formed in the placenta, which nourishes the egg after it has been fertilized and becomes attached to the uterine wall. Continue Reading “Human Chorionic Gonadotropin (HCG): The Pregnancy Hormone”

Fetal Development

 

Calculating the day your baby begins to develop and keeping track of your pregnancy dates can be a challenge. The development of pregnancy is counted from the first day of your last normal period, even though the development of the fetus does not begin until conception. Pregnancy is calculated from this day because each time a woman has a period, her body is preparing for pregnancy. Continue Reading “Fetal Development”
