Calculate Pregnancy Age

Often, you ask your pregnancy to make sure when you hold a special ceremony in connection.

Confusion over gestation because the doctor's count doesn't match of yours. Sometimes, it causes anxiety in you. You fear, the baby is born passing of time or even too young.

Let's try to equate the views about the pregnancy. In the menstrual cycle, an egg is released by the ovary fourteen days before the next menstruation. This event is called ovulation. The egg will fit into the channel which fertilization occurs.

The next is, fertilization result will be transported into the uterus. If pregnancy doesn't occur, the egg degenerates and is expelled from the uterus along with menstrual blood. However, if fertilization occurs, the result will grow into an embryo through cell division.

Pregnancy is usually calculated by the unit of weeks starting from the first day of last menstruation. Because ovulation generally occurs two weeks after the first period, and fertilization occurs shortly, the embryo age is roughly two weeks younger than the actual gestational age.

In other words, if you're expressed pregnant for four weeks, the embryo is two. If the menstruation is irregular, difference in gestational age may actually be more than two weeks. To make it easier, if you miss period two weeks, your pregnancy will a doctor write six weeks.

An averagely gestational age is 266 days calculated from the occurrence of conception. The estimated date of delivery is usually calculated by subtracting three months from the first day of menstruation. The day is added by seven, and the year is by one.

For example, if you're pregnant with the first day of the last menstrual period at July 23, 2014, the estimated date of birth is April 30, 2015.

It's estimated that only ten percent pregnancy, the childbirth is according to the estimated due date. Fifty percent will labor within one week around the estimated date, and ninety percent will do within two weeks. Therefore, delivery less or more than two weeks of the estimated date is considered to be normal.

Generally, determining a pregnancy can be done by a blood or urine test. Pregnancy test using the enzyme-linked immunosorbent assay can detect early, quickly and easily although at that time, the human chorionic gonadotropin (hCG) in urine is still low.

Some sensitive pregnancy tests can detect hCG when the level is still very low, i.e., one and a half weeks after a cycle of fertility. The examination takes about a half hour. During the first sixty days, under conditions of normal pregnancy with one fetus, hCG will increase two times every two days.

You often forget the first day of the last menstrual period. It'd be difficult for a doctor to calculate the age of the pregnancy. For that, there're several ways to determine gestational age:

1. Fetal heartbeat can be heard through a special stethoscope or an instrument called a Doppler. The fetal heart can be detected with a stethoscope when the gestational age is about eighteen to twenty weeks, and with a Doppler is during twelve to fourteen weeks.

2. You can feel fetal movement, generally when the gestational age is sixteen to twenty weeks. You who've been pregnant before can feel the movements earlier.

3. Enlargement of the uterus can be seen using ultrasound when the gestational age is approximately of six weeks. Fetal heartbeat can be seen when aged six weeks although it's not clear. Ninety-five percent of the beat can be seen clearly when the gestational age is of eight weeks.

Hopefully, you're not wrong again in determining the ceremony.
