How Many Weeks Am I Based On My Due Date

It makes sense to think of pregnancy as conception, because this is the moment when the sperm and egg combine to form the little bundle of joy.

A Cheat Sheet To Pregnancy Hormones

It is common practice to date the pregnancy to the first day of the last menstrual period because most women do not know the exact date of conception.

Of course, this isn’t the most accurate way to date your pregnancy (more on that below). But this is the most popular way to learn how to calculate date of birth and gestational age.

Calculating the onset of pregnancy according to the last menstrual period is not a very accurate method because many factors affect the time of ovulation. Imagine this scenario:

In the example above, both women started menstruating on the same day, and both women had two weeks to live. But one woman is four weeks pregnant and the other is five weeks pregnant.

As you can see, the answer to the question of how many weeks pregnant am I is not as simple as you think.

Going back to the hypothetical scenario above, it’s easy to see why embedding is the most accurate way to calculate distance. Here’s the trick: Even if you know when you’re ovulating, it’s very difficult to know for sure when implantation will occur.

After fertilization (when the sperm fertilizes the egg), the fertilized egg (called the blastocyst at this point) travels through the fallopian tube to the uterus. Compared to the tiny blastocyst, the uterus is huge! The blastocyst has many places to implant and may lodge in the upper part of the uterus or make a longer journey to the lower part.

Because of the time it takes to travel to the implantation site, most experts agree that implantation occurs about nine days after conception, but can occur anywhere from six days to 12 days after conception. (source, source)

But there is good news! Although there is no test that will determine the exact day of implantation, your body can show that implantation has occurred:

The most accurate way to determine the gestational age after implantation is to use the date of ovulation. If you know when you ovulated, you have a much better chance of answering the question correctly.

But it’s also not a foolproof method – you can miss a few days or miscalculate when trying to figure out when you ovulated. (For a more accurate answer, visit our ovulation calculator.)

What if you don’t know your last menstrual period? Or your menstrual cycle is so irregular that you can’t even predict when you’ll ovulate? Don’t worry! A dating ultrasound can help; In fact, doctors often use a dating ultrasound as a tool to confirm the LMP method.

Pregnancy At Week 35

Healthy embryos grow at a fairly predictable rate during the first trimester, so a measurement from head to ass can give you a more accurate estimate of how many weeks you are. Crown and torso refers to the distance between the head (crown) and the baby’s bottom (rump). If the dating ultrasound is done before the 13th week of pregnancy, its accuracy is +/- five to seven days. (source) In the second trimester, this jumps from +/- seven to 10 days. (source)

If you get an official due date on your appointment ultrasound, using our reverse date calculator to find out when you might get pregnant will give you a much better answer as to how many weeks pregnant I am.

What if your date of birth (relative to LMP) is different from ultrasound? Or if there are four different deadlines?! (Yes, there are four different birth dates: LMP, implantation (when you feel cramps), ovulation, and ultrasound.)

In these cases, the obstetrician or midwife may adjust the date of birth according to the ultrasound, as the dating is considered more accurate. (See this post to see how accurate the deadline is.)

Note: Many healthcare providers will not be able to change your due date unless you are more than a week apart, but this may affect induction later in your pregnancy. If you think you need to change your due date, ask for an appointment ultrasound or see your doctor to change your due date. If the due date is not set, you may hear the promos after a “delay” of a week, even if that is the actual due date.

And while there is definitely some logic behind it, the medical community asks, “How many weeks pregnant am I?” That’s not how he answers your question.

If someone asks you how old you are, whether it’s 30 and 3 days, 30 and 364 days, you say you’re 30. Even the night before your 31st birthday, you say you’re 30, even though you’re almost 31.

So how many weeks are you pregnant? Most mothers answer this by saying how many weeks and days you are:

Scientists who study assisted reproduction. Embryonic age is based on the day of conception, which is usually 14 days shorter than the gestational age, but varies depending on the individual’s menstrual cycle (2). Embryonic age is not commonly used in pregnancy care, but when you see this term, you know that a fetus is two weeks shorter than gestational age.

LMP can be an important turning point for your pregnancy. The menstrual cycle begins on the first day of menstruation, a date that health professionals refer to as the “last menstrual period” (3). During pregnancy, this date may appear as ‘LMP’ on your paperwork.

(3). It begins with LMP, which is the first day of menstruation. This is the period when your ovaries are at their most dormant as your body prepares for all the hormonal changes of the next cycle (2).

Because every body is different and every cycle is unique, the estimated due date based on your last menstrual period is unlikely to be accurate unless you have a planned induction or cesarean section. If your estimated due date is based on your last menstrual period, this assumes you have 28-day cycles and ovulated on day 14 (1). A few factors such as cycle length and ovulation date (3-7) make this method less than perfect:

Approximately 4-5% of women and pregnant women give birth on their estimated due date (1, 8, 9). There are two reasons for this: Pregnancy is a varied and complex process, and pregnancies clearly vary from person to person and from pregnancy to pregnancy (1).

Research shows that the best time for an ultrasound examination is between 11-14 days of pregnancy. shows that there are weeks (9). Early pregnancy ultrasounds may be referred to as “date scans” by your healthcare provider because they take into account the size of several different parts of the fetus to determine the approximate gestational age.
