A pregnancy week calculator is a device that helps to determine the expected date for the onset of labor. The date is also known as the estimated due date. Once you know that you are pregnant after taking the pregnancy test, the next question popup in your mind is when precisely your baby will arrive. This is where pregnancy week calculators drive-in is known best for due date estimation. Your curiosity to know by which date your baby will open his eyes in this new world makes your doctor access an approximate due date. Still, you can also do it yourself by using a pregnancy week calculator, also called a due date calculator or pregnancy days calculator. Don't get confused with different names. All work the same and have similar functions.


You can use two types of pregnancy week calculators to determine the due date depending on these factors. If you have already passed the phase of the first ultrasound scan, you can use the Due Date by Ultrasound Calculator, but if you have conceived through IVF, you should use IVF or FET Due Date Calculator. Keep this in mind, ultrasound is done to determine the ovulation date, but it only suggests gestational age, and hence, it's not considered perfectly accurate. At the same time, a perfect date of conception is usually determined in the case of In Vitro Fertilization (IVF).


Weeks I Am Pregnant From My Last Period?


If you know the date of the first day of your last menstrual cycle or the date of the day you conceive, you can easily estimate the weeks you are pregnant from your previous period by using pregnancy week calculators. You can figure out your due date and weeks you are pregnant by using several ways, including:


Last Menstrual Period (LMP)


Pregnancy usually continues approximately 40 weeks (9 months) from the first day of your last menstrual period. Correspondingly, the numeral of weeks that have passed showed which week of gestation you are in. Count 280 days from the first day of your last period to determine the due date.

Day/Date of Conception


As likely as not, you conceived throughout the time of ovulation, which is around about day 14 after the average menstrual cycle of 28 days. Suppose you are aware of the exact date, count 266 days which are about 38 weeks roughly, to determine the approximate due date. Pregnancy week calculators are designed to do all this counting for you.


Ultrasound


A phase comes in your pregnancy when you likely go for an ultrasound scan. This facilitates your healthcare office to examine fetal growth and development. An ultrasound scan provides the exact accurate evaluation of how many weeks you are pregnant and what is the approximate date when your labor is anticipated to begin. This method is most reliable and valuable when you forget the date of your last period or if you are facing the problem of irregular menstrual cycles.


Don’t get demented between the weeks of pregnancy and the baby's gestational age because both are different. Conception mostly takes place about 14 days into your last menstrual cycle, and pregnancy is calculated from the start of that cycle. There is two weeks difference in the gestational age of the baby. For instance, if you are eight weeks pregnant, your infant's gestational age is only five weeks.


Your Pregnancy Week-By-Week


When you are pregnant, your baby is changing, growing, and developing day by day, and your body is staying in stride. The pregnancy week calculator helps you track and better understand the weeks, months, and trimesters of your pregnancy. With the passing of every week, month, or trimester new physical and developmental changes occur to you and your baby. There are three trimesters in your total pregnancy:

  • First trimester
  • Second trimester
  • Third trimester

The rest of the work is performed by the calculator. It plus 280 days (40 weeks) to the first date of your last menstrual cycle (presuming a 28-day cycle). Your menstrual and ovulation time is counted as the two weeks of pregnancy.


This is why select the pregnancy week calculator as it determines the exact ovulation period. If your labor occurs at your due date, your baby's age is only 38 weeks, not 40.


Accuracy Of Pregnancy Week Calculator


Pregnancy Week Calculator provides an estimated due date. But keep in mind that it is only an approximate date of the baby's arrival, and only 4 per cent of babies are born on their due date. The accuracy of the due date also depends on how precisely the mother recalls the day of intercourse if she has regular menstrual cycles, ovulation periods, and ovulation takes place on the exact 14th day of the ovulation cycle.
