Can An Ultrasound Determine A More Accurate Due Date

When can my baby’s due date be determined?

Your doctor may adjust your due date during a dating ultrasound, which typically occurs during one of your first appointments. Since healthy embryos grow at a highly predictable rate during the first trimester, measuring the length of the embryo can provide a more accurate estimation of how many weeks pregnant you are.

If your dating ultrasound does not match the due date based on your LMP, your doctor may adjust your due date according to the ultrasound, as this is typically considered more accurate.

Sex At Week 5 Of Pregnancy

What Is A Ultrasound Scan Why Is It Used And Not Used

An ultrasound exam uses high-frequency sound waves to create a picture of the baby and the placenta. While the sonogram refers to the picture and ultrasound refers to the exam, most people use the terms interchangeably.

In the United States, most pregnant women are offered their first ultrasound scan by their doctor or midwife between 9 and 14 weeks of pregnancy.

The first scan is used to determine how far along you are and how many babies youre carrying!

First trimester ultrasounds help identify the babys heart rate, umbilical cord, the placement and size of the placenta, and confirms how far along your little one is.

The longer you wait for your gender scan, the better chance the technician has of being able to visually determine the babys gender provided your little bean cooperates.

Good ultrasound technicians claim upwards of 95% success rate.

The technician is looking for physical markers that might indicate an abnormality, versus typical development.

Ultrasounds will not detect every birth defect, and a typical ultrasound doesnt guarantee a healthy baby.

The diagnostic benefits of ultrasounds and the visual image parents can see, make ultrasound a valuable pregnancy tool.

If according to these ultrasounds, your baby appears to be developing typically, you will probably not need additional ultrasounds during your pregnancy.

Some women might have a third-trimester ultrasound if they are advanced maternal age , or if they have low amniotic fluid.

They will also check your babys head, face, limbs and count your babys toes and fingers. Using the ultrasound, your doctor or midwife can measure the amniotic fluid and check the placenta.

What Exactly Is The Date Of Conception

The date of conception is the day that the egg and sperm meet.

Women who track their ovulation may know their exact date of conception. But for many women, date of conception can be tricky to pinpoint.

Sperm can live in a womans body for up to five days, and the ovum can live for up to 24 hours after being released. In other words, you have a six-day window where you could potentially get pregnant each month.

Do you already know your due date but want to know when you likely conceived? Try our reverse due date calculator.

How Does Hcg Behave In A Normal Pregnancy

In a normal pregnancy, hCG will begin to rise rapidly once successful implantation has occurred. For the first four weeks of pregnancy, hCG will typically double every 48 to 72 hours. From week four to six, it may take three to four days to double. Once you have reached week 10, hCG no longer doubles but instead remains steady for the rest of the pregnancy. It can even slowly begin to slowly decline after week 17.

If hCG does not rise at the right pace, this could potentially be a cause for concern. Molar pregnancies, ectopic pregnancies, and miscarriages are all potential risk factors in cases where hCG levels are too high or too low. Regular hCG testing and monitoring combined with ultrasounds by your doctor can help you gain better insight into whether or not your pregnancy is healthy and developing normally.

How Soon Can You Take A Pregnancy Test

At-home pregnancy tests are regulated by the Food and Drug Administration , meaning their accuracy and labeling is evaluated before they reach store shelves. When it comes to the accuracy of at-home pregnancy tests, research shows if the test is used as directed, an inaccurate result is rare. While false-positive pregnancy test results are uncommon, if you do receive an inaccurate result, its more likely to be a false-negative. In this case, its likely youre testing too early, before HCG can be detected.

For most women who have a regular menstrual cycle, a pregnancy test could be taken on the expected day of the period, says Dr. Merhi. The earliest would be the expected day of the period however, I usually tell patients to wait at least a few days after the expected day of the period in order to lower the chances of having a false result.

Its worth noting that at-home pregnancy tests accuracy claimsmany of which advertise an accuracy rate of 99% from the day of the expected periodare based on data used in a sterile laboratory testing environment. If you think you received an inaccurate result, you can either wait and test again a few days later or see your doctor for a blood test, which can detect HCG earlier than at-home tests and has an accuracy rate of 99%.

What Do High Hcg Levels Mean For A Pregnancy

If your hCG levels are above the normal range, this could indicate any of the following.

Twins or multiples

If you are carrying twins or multiples, it is normal to have hCG levels that are higher than the normal range. While there is no specific chart or figure for how high hCG levels can reach when carrying twins, some doctors suggest that it can be up to 30-50% higher than a normal pregnancy.

Molar pregnancy

Molar pregnancies occur when there is an abnormal growth of tissue in the uterus due to a genetic error. In a complete molar pregnancy, the emerging placenta grows and produces hCG, however there is no embryo. In a partial molar pregnancy, an embryo does exist however it has severe birth defects.

Molar pregnancies should be treated immediately by a doctor. In addition to elevated hCG levels, a molar pregnancy may also be accompanied by bright red or brown vaginal bleeding, pelvic pain, and severe nausea.

Down syndrome

Higher than normal hCG levels can also indicate that your pregnancy may be at risk of Downs syndrome. However, your doctor will need to conduct further blood testing and ultrasounds throughout your pregnancy to determine how high this risk level is.

What Are The Risks Of Labor Induction If Im Not Post

Induction is often the safest option for post-term pregnancies, but it may not make sense to discuss induction until you are confident that you are truly post-term. This is because the drugs used for labor induction do carry some risks. They can cause abnormal contractions, which can adversely affect the babys oxygen intake and heart rate, and can increase the likelihood of post-birth hemorrhage and infection. Also, theres always the chance that the induction fails, in which case a c-section will likely be the next step.

In the case of true post-term cases, the benefits generally outweigh risks, but its important to be aware of this cost-benefit assessment.

Whats The Most Accurate Way To Date A Pregnancy

Going back to the hypothetical scenario above, its easy to see why the most accurate method for calculating how far along you are would be by implantation. Heres the catch: Its very hard to know when implantation occurs with certaintyeven if you know when you ovulated.

After conception , the fertilized egg travels from the fallopian tubes into the uterus. Compared to the tiny blastocyst, the uterus is huge! There are many places for the blastocyst to implant, and it can implant in the upper area of your uterus or it may take the longer route to the lower area.

Because of the time it takes to travel to the implantation location, most experts agree that implantation occurs about nine days after conception, but it can range from as early as six days to as late as 12 days after conception.

There is good news though! While there is no test to determine exactly what day implantation occurred, your body may give you hints that implantation has occurred:

Calculating From Your Last Menstrual Period

Pregnancy test positive and nothing on the ultrasound ...

Pregnancies are 40 weeks, but you’re actually pregnant for only 38 of them. Why? Because for doctors, the pregnancy clock starts its countdown from the day of your last missed period â the tricky date responsible for the infamous two-week wait when trying to conceive.

The absolute best way to date a pregnancy is from the date of conception, but Plancher says that can be hard to track, especially if you have sex often .

But the day of a missed menstrual period is also hard to track. I know that my period likes to take her sweet time arriving some months, while on others, she’s way ahead of schedule. If you’re the lucky lady with a Swiss cycle, I’ve got great news: you can figure out how far along you are, simply by counting backwards.

“If someone gets their period every 28 days, you can probably get a pretty good due date based on their last period, but thatâs rare. I like to confirm their LMP due date with an early ultrasound,â Plancher says.

Disclaimer About The Calculator

Our calculator strives for the highest accuracy, but your pregnancy progress may differ from the calculator’s results for several reasons including possible miscalculation errors in input data individual variations in the timing of ovulation, and/or conception.

The information provided regarding pregnancy progress and fetal development is a guide through the weeks. It is not specific information for a specific individual but serves as a general guide only. As each pregnancy differs, any dates, weights, and lengths should be considered general information for interest only.

Our week-by-week guides use both standard and metric units of measure including pounds and kilograms.

Why Pregnancy Is Counted From The Last Menstrual Period

Pregnancy is counted from a women’s last menstrual period because the start of a period is easily observable and usually known to a woman whereas the date of conception is much less likely to be known.

Historically, the first day of the last menstrual period became the date from which pregnancy is counted even though conception occurs about two weeks later.

The LMP formula is good for working out an initial age of pregnancy but ultrasound is more accurate. The age of pregnancy may be revised following your ultrasound scan.
