Pregnancy calculator: in week, month and quarter

If you are going to be a mother, you are bound to worry about your pregnancy. Pregnant women often have a tendency to monitor time – to determine at what stage they have reached their pregnancy and how much time is now left to give birth to a baby. Many women get confused because of the math involved in calculating the due date or gestational age on a month, week, and quarterly basis. This article is going to tell the pregnant women about the concept of Pregnancy calculator of their pregnancy, which is quite easy.

How is the due date of pregnancy calculated?

A full pregnancy is generally considered to be 40 weeks and Estimated Date of Confinement (EDC) or Estimated Due Date (EDD) is calculated from the date of the last menstrual period (LMP). 280 days are added to the last menstrual date and a possible due date or due date is set. In a full-term delivery, the baby is usually born around the estimated delivery date. Since the exact time of ovulation is not known, this calculation only gives a rough estimate of the delivery date, and in which only 5% of children are born on their due date.

Why is pregnancy counted from the start date of the last menstruation?

The period of ovulation, at which time fertilization or fertilization occurs, usually occurs two weeks after menstruation. Many people do not know the exact date of conception, but most remember the date of their last menstruation. To get an estimated due date, a forty week gestation is added to the last period date from which the due date is calculated. During the first two weeks after the last period, you will be ovulating and ready for fertilization. However, these non-pregnant periods over a time period of 40 weeks have also been added to the LMP. Additionally, this calculation is based on the assumption that your menstrual cycle arrives every 28 days.

How many weeks in a full pregnancy?

According to experts, a full pregnancy lasts up to 40 weeks. This is the basis on which the due date is also calculated. However, if a child lives 39 weeks inside the mother’s womb, it is considered to be full-term and fully developed. Delivery can occur anytime between the 39th week and the 41st week.

How many quarters are there in pregnancy?

The entire period of pregnancy is divided into three quarters of three months each. The 1 to 3 months of pregnancy fall under the ‘first trimester’, the ‘second trimester’ in 4 to 8 months of pregnancy, and the ‘third trimester’ of pregnancy in 7 to 9 months. Usually, there are some specific changes in each trimester, and this classification helps to understand pregnancy better.

How many weeks are there in a quarter?

There are approximately 13 to 14 weeks in each trimester. However, the correct way to divide the quarter is: Week 1 to 13 – First Quarter, 13 to 27 – Second Quarter and Week 28 to Delivery have been considered as the third quarter. The last quarter is one more week than the other two quarters.

Week to Month Pregnancy Chart

Different people calculate the stage of pregnancy in different ways. Some people count it in months, some in quarter and some in week. Doctors usually calculate pregnancy in weeks, as they check the child’s development on a weekly basis. Most commonly occurring mothers have difficulty counting in weeks. The list below can be very helpful in understanding the weeks of pregnancy and the months related to them. Important milestones in the list are based on gestational age, not on fetal age.

Quarter month week important break
First 1 1 to 4 During this period a woman conceives or becomes pregnant.
2 5 to 8 baby’s heartbeat starts
39 to 13 baby organs and structures grow
Second 4 14 to 17 baby’s penis develops
5 18 to 21 Baby starts kicking and is aware of the sound around
6 22 to 26 hand reflexes develop
Third 7 27 to 30 fetuses develop breathing capacity.
8 31 to 35 nails are fully developed
936 to 40 baby ready for delivery

How can you calculate pregnancy week?

Calculating the exact week of pregnancy is something that many women find very difficult. For example, if you are in the middle of ten weeks of pregnancy, your doctor may say that you are nine weeks pregnant. However, developmental milestones correspond to the tenth week of pregnancy. This confusion arises due to the way it is counted.

Like the calculation of age, the week usually completed is considered gestational age. The number of weeks in your pregnancy is different from the week of pregnancy you completed. Therefore, in stating the stage of your pregnancy, you can say that you are nine weeks pregnant or in the tenth week of pregnancy. Both are the correct and accepted methods of determining the stage of pregnancy.

How do doctors calculate pregnancy week?

By the way, the last period method to calculate the due date has been widely accepted, with doctors sometimes estimating the week of pregnancy by alternative means to determine the actual fetal age. This is particularly useful for women whose menstrual periods are irregular and they do not remember their last menstrual date. The following two methods are followed to assess the age of the fetus.

Physical test

Doctors usually perform a physical examination of the mother to determine the size of the uterus. Especially in the first trimester it gives them proper information about the week of pregnancy. The distance between the fundus and the pubic bone varies in the first few weeks of pregnancy and doctors use this measurement to estimate the age of the fetus. This method does not identify other pregnancy complications and can be quite uncomfortable for the mother.

2. Ultrasound Dating

Another approach is in which doctors determine the number of weeks of pregnancy by image of a growing fetus using ultrasound waves. In this method, the distance from head to hip, head to toe, and diameter of the amniotic sac are measured and the child’s age is determined. Through this method, the age of the fetus is determined correctly.

Does pregnancy last for nine months?

The total time period of pregnancy from the last period is considered 40 weeks. If each month is considered to be four weeks, then it seems like ten months. However, in this calculation, it is to be remembered that two weeks after the last day of menstruation, actual fertilization and conception take place. Additionally, some months have 31 days and some have 30 days, except February. As an average, every month is not 4 weeks but 4.4 weeks. Based on this, the effective pregnancy period from conception to delivery, taken as 40 weeks, changes to nine months and one week.

How to know which week of pregnancy you are in now?

Many mothers often suspect that ‘How many weeks am I pregnant?’ To calculate the week of pregnancy, the first day of your last menstrual period is considered the starting date of your pregnancy. Calculating the number of weeks from the first day of the LMP reveals the gestational age of the child.

What if you don’t know your LMP or your menstruation is irregular?

In the event that you do not know the exact date of your last menstruation or if your menstrual cycle is irregular, doctors estimate the age of the fetus through ultrasound imaging. Parameters such as length from head to back and measurement of fetal sac give information about gestational age. The expected delivery date is given by the doctor, depending on the age of the fetus.

How is pregnancy week calculated after IVF?

The calculation of the due date for pregnancy achieved through in vitroofertilization i.e. IVF differs slightly from natural fertilization of pregnancy. In this case, the information available for calculating the due date is accurate. In IVF pregnancy, the date of ovulation (the date on which the egg was taken) or the date on which the embryo was implanted appears to be correct. Apart from these two dates, the due date is also calculated from the last period, the third day or the fifth day of IVF treatment.

How accurate is the pregnancy due date calculated?

The due date of pregnancy is calculated as a rough estimate of the probable date at which the baby may be born. Only 5% of children are born on the due date, while all others are born before or a few days after. Lack of exact date of last period and variation in exact date of fertilization may cause a difference in actual delivery date and expected due date.

It is very common for pregnant women to have anxiety around the due date. The fixed dates that doctors prescribe are usually an approximate time frame for all preparations for childbirth. Often weeks, months or quarters are used to determine the stage of pregnancy and you can choose any method you find convenient.

What happens if LaborPen is too early or too late?

There are many cases in which LaborPen may arrive much earlier than your due date, or there are no signs of labor even after the due date has passed. There are some preconceptions that your doctor may take in such a situation.

  1. early labor
    Premature birth means a birth that occurs before the 37th week. If this problem is not due to an incorrect calculation of the due date, and the baby is not fully developed for birth, then the doctor may try to delay labor to give your baby some more time in the womb. However, in cases where this is not possible, after the birth of the child it is closely monitored to ensure good health.
  2. Late LaborPen
    Delayed birth occurs when childbirth does not occur even after the 41st week of pregnancy. This can be a cause for concern, as it can cause complications for the health of the mother and the child and even increase the risk of having a dead baby. Will try the way of
