Dating Pregnancy Using Ultrasound
Ultrasound in the first trimester is the most accurate method of dating pregnancy. During the scan, baby is measured and the age of pregnancy is estimated by comparing baby’s size against recorded averages. If there is a significant difference between gestational age according to LMP and gestational age according to the ultrasound, you may be given a new gestational age and due date based on the ultrasound measurements.
Your pregnancy may also be dated by ultrasound measurement if an LMP formula was not appropriate for your pregnancy for any reason. LMP formulas are not suitable in several situations including the following: LMP is not known or is not certain, birth control pills were taken in the two months before LMP, the menstrual cycle is irregular, you are carrying multiples .
Although the age of pregnancy based on ultrasound measurements is more accurate than the age of pregnancy based on LMP, both are estimates and not definitive statements.

Determining If Labor Is Premature
Babies who are born too early are at risk for numerous health problems. There are steps we can take to slow or halt preterm labor. With that said, there are also risks to the medications used to stop preterm labor, both to the mother and the baby.
You and your doctor have to decide together when the risks of allowing labor to continue to outweigh the risks of intervention. This is partially determined by knowing which week of pregnancy you are in.
There are also risks to the baby and mother if a pregnancy goes on for too long. Post-term pregnancy is when birth does not occur by week 42 . If this happens, your midwife or doctor may decide to induce labor.

How Did I Get A Positive Result On My Pregnancy Test
If you got a positive result on your pregnancy test, that means your placenta is producing human chorionic gonadotropin that’s what the test looks for. It only happens when pregnancy occurs.
- If you have hCG levels less than 5 mIU/ml, then you are considered a non-pregnant woman. That’s because you don’t produce it if you’re not pregnant.
- When the levels are 25 mIU/ml or higher, you will be considered pregnant. If you know you are pregnant and then notice that your levels are low, there are three possibilities: miscalculation of your pregnancy dating, miscarriage, and an ectopic pregnancy.

What Is A Due Date
It takes about 38 weeks for human babies to develop fully in the womb. Your due date is the day youre expected to give birth based on this 38-week gestation process.
But keep in mind that healthcare providers consider a pregnancy to be full-term anywhere between 37 and 42 weeks. Babies can be born at any time, and many factors play a role in determining when you go into labor and when your baby will actually enter the world.
Using Date Of Conception
The window for conception ranges from a few days before ovulation to a few days after. A typical menstrual cycle of 28 days means you ovulated around day 14. So if you know the exact date of conception, count 266 days to get your due datebut, of course, understand that baby might actually arrive a few days before or after, says Skeete Henry.
Counting from date of conception isnt always the most precise method for determining how far along you are, since its often difficult to know, with absolute certainty, when you actually conceived. Were not just talking about the day you had sex sperm can live inside your fallopian tubes for up to five days, so its possible to conceive up to five days after intercourse.

How Soon Can I Take A Pregnancy Test
A missed menstruation cycle is one of the earliest signs of pregnancy. Thats why we usually recommend waiting until youve missed your period before taking a pregnancy test. You can purchase low cost, high quality pregnancy tests here. If you cant wait that long and you know the day of your last period we can calculate possible conception and your pregnancy due date.
How To Know When You Conceived
In general, there are a few ways to determine your conception date. No method is 100% accurate, but some are more reliable than others.
Ovulation
The first way to find out your conception date is to determine when you were last ovulating. In general, women can only conceive when they are ovulating that is, when their ovaries release a new egg into their fallopian tubes for fertilization. That means you can use your ovulation dates to try to determine when you became pregnant.
Ovulation usually occurs about two weeks after your menstrual period and lasts for two or three days. This means you can sometimes determine when you conceived based on your ovulation cycles simply determine when your last menstrual period was and add approximately two weeks.
However, this method isnt always accurate. Not all women have the same cycles of menstruation and ovulation, some womens menstrual cycles are irregular, others have ovulation periods closer to or further from their menstrual period and some women simply arent sure when their last period was. In other words, calculating conception based only on your body cycles can be difficult.
Intercourse
Another way to learn your conception date is to try to determine the last time you had sexual intercourse. Unfortunately, this method isnt totally accurate either. Conception is a process that takes time and a mans sperm can actually stay alive inside your body for up to a week after sex.

Tracking Progress: How To Tell How Many Weeks Pregnant Are You
How do I know how many weeks pregnant I am? you ask? Your last menstrual period comes in handy not only for estimating your due date its also used for zeroing in on how many weeks pregnant you are. Youll want to keep track of it in order to monitor your progress as your baby grows.
To figure out your pregnancy week, start counting from the first day of your LMP, which would be considered 0 weeks and 0 days, says Joseph Adashek, MD, FACOG, a perinatologist and co-owner of Desert Perinatal Associates in Las Vegas. The day after you bleed, you are 0 weeks and 1 day pregnant. On the day you conceive, you are 2 weeks and 0 days. After 2 weeks and 6 days, youre considered 3 weeks pregnant, and so on. This is also known as your babys gestational age.
Sounds a bit illogical, given that youre obviously not pregnant until after youve ovulated, right? But in the old days, a gestational age was helpful before ultrasounds could offer clues as to exactly how far along you are, Adashek says. These days, gestational age is still used uniformly around the world to determine how many weeks pregnant you are, especially since many places still dont use ultrasounds routinely. The gestational age is also the age automatically reported by the ultrasound, should your doctor use one.

A note from Cleveland Clinic
A due date calculator helps you plan for your babys arrival. Keep in mind that a due date calculator is only an estimate. Youll need to see your provider to confirm the date. Your due date may change when you have a prenatal ultrasound. Your provider may even change your due date more than once during your pregnancy, but it usually only changes by a few days. Knowing when to expect your new family member allows you to prepare mentally and physically. An accurate due date also helps your provider monitor your health and the health of your baby.
