When Is My Due Date

If the first day of your last period is accurate, you can calculate by subtracting three months and adding seven days to the first day of your last period.
Your doctor will want to determine the exact date of pregnancy as early as possible. Expected delivery times* affect the timeliness and accuracy of many medical tests. It also affects many medical decisions during pregnancy.
* Estimated due date is a medical term used to determine due date. This is often referred to as your EDC.

You will be asked about your menstrual cycle to calculate your expected due date (EDC).
If the decision is made to use a fixed period based on the menstrual cycle, your provider will want to know the first day of your last period and will want to know if you are confident with that date.
Example: If you are 10 weeks pregnant, and you show that you are 16 weeks, an ultrasound will be done to determine your due date. This is because there is a significant difference between your menstrual cycle and your physical exam.

What questions do I get about my period? 1) When was the first day of your last period?
This will determine if you have a 28-day menstrual cycle. During ovulation, an egg is released from the ovarian follicle.
4. Did your last period start on the right day and last the usual number of days?
This will help you determine how reliable it is for timing your period. If your menstrual cycle is very consistent at 28 days in length, you will ovulate regularly between cycles.

Menstruation can be irregular when it starts (menstruation) and ends (menopause). This information can help you determine how accurate your last period was.
7. Did you take a home pregnancy test before this trip? If so, what day did you first test positive?
Infertility is often accompanied by irregular periods, delayed ovulation and anovulation (absence of ovulation). If you are pregnant without fertility treatment, this information may be helpful.
11. Did you take birth control pills or other hormonal contraceptives when you were pregnant?
How Realistic Is Your Due Date?
The most accurate information for calculating the due date is provided by an ultrasound performed at 12 weeks of pregnancy. Because the ultrasound doctor can see the changes in a short time.
And the ultrasound performed in the third trimester is very inaccurate, because the fetus is fully developed and the changes in the image are very small.
The reason for accurate timing of first trimester ultrasound is that ultrasound results are visible in a few days.
Specific first trimester ultrasound results are listed below. They provide information about fetal development and well-being:

The gestational sac can be seen as early as the fourth week of pregnancy. However, it often becomes apparent between the fifth and sixth week.
This is the first result that confirms that the pregnancy is developing in the uterus. This ultrasound result is often compared to a blood test called hCG (human chorionic gonadotropin).
It was determined that if the blood count exceeds 2500, an intrauterine cyst should be visible.
Otherwise, it’s not a problem because lab measurements can vary, and if someone has twins, the hCG level will be higher.

If your hCG reaches 2500, the main reason your doctor will want to confirm an intrauterine pregnancy is to rule out the possibility of an ectopic pregnancy.
This is a pregnancy that has developed but has not implanted in the uterine cavity. A pregnancy that occurs outside the uterine cavity is called an ectopic pregnancy. An ectopic pregnancy usually occurs in the fallopian tube.
It is very important to detect an ectopic pregnancy as early as possible so that treatment can begin before the pregnancy continues and leaves the fallopian tubes.
Ultrasound can detect a fetal heartbeat as early as 5 1/2 weeks. But until 6 or even 7 weeks, the heartbeat is not noticeable.
Evidence On: Due Dates
This yolk sac result confirms the presence of a developing embryo inside the gestational sac. The yolk sac provides the placenta with nourishment for the fetus.
The yolk sac and fetal pole can be seen on a transvaginal ultrasound at 5 1/2 to 6 1/2 weeks.
At 7-12 weeks gestation, ultrasound identification is not based on the gestational sac, fetal nucleus, or yolk sac. At this stage of pregnancy, the coronal length is the ultrasound measurement used to calculate the term.
That’s because second-trimester ultrasound changes from week to week are subtle compared to the dramatic changes in the first trimester.

In the second trimester, periodic ultrasound is performed to determine the diameter of the fetal head (biparietal diameter) and other features of fetal development. The accuracy of these fetal growth parameters is only accurate for 11 days.
*The accuracy of ultrasound depends on the specialty of the ultrasound and the quality of the equipment.
For the same reasons listed above, third-trimester ultrasounds are imprecise and can be wrong by up to three weeks. During the third trimester, there is very little change in fetal development from one week to the next. This is the reason for the impreciseness of the term.
However, a third trimester ultrasound is the only dating option if you had your first prenatal appointment in the third trimester and your due date does not match your last period.
Calculating Due Date Of Pregnancy
