Calculating From Your Last Menstrual Period
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.
What Is A Due Date Calculator
A due date calculator helps you estimate when your baby will be born. By calculating your due date, youll have an idea of your babys birthday. But keep in mind that your due date is only an estimate. Very few babies are actually born on the day they were due.
Knowing your due date is important for several reasons. It helps you plan and prepare for your babys arrival. It also gives your provider essential information they need to monitor your health and your babys health.
You can calculate your due date at home using a couple of different methods. But these methods arent always accurate. When you visit your provider, they may give you a different due date based on the size of your baby on ultrasound and the date of your last period.

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 Do I Calculate How Far Along My Pregnancy Is
Knowing exactly how far along you are in your pregnancy can be confusing. Pregnancy symptoms are different for each woman and make for an unreliable guide to determine where you are in the gestational period. So exactly how does one determine their date of conception or due date?
When Was Your Last Period?
Knowing the first date of your last period is key. This is the date most commonly used to determine gestational age. For most women, this date is about two weeks before ovulation and conception occurred. Conception typically takes place between eleven and twenty-one days after the first day of your last period.
Most women dont know their exact day of ovulation, but they usually know when their last period began, so this is the most reliable way to determine how far along you are and when you would be full term.
How Do I Calculate My Due Date?
To account for the two weeks prior to conception, doctors take the first day of your last menstrual period and add 280 days todetermine the due date.
From there, you can also determine how far along you are by counting how many weeks it has been since the first day of your last period. For instance, if your last period began on August 1st, you would be eight weeks on September 26th, thirteen weeks on October 31st, and your due date would be May 8th. This example is based on a 28-day cycle. If your cycle is longer or shorter, it will change slightly.

Nope! You can rely on the due date suggested by your last menstrual period, but your healthcare provider may schedule one anyway. Your doctor may do it for other reasons, but for figuring out dates, its really not necessary if she isnt concerned and theres nothing odd happening, says Scurfield.
Do Not Give Vaccines Or Drugs
When pregnant, cats are strongly advised not to be given vaccines. This is because it can inhibit the growth of kittens. Besides, the administration of helminthic drugs, antiquarian drugs, and others can harm the fetus they contain.
This can be one of the causes of miscarriage as well as birth defects. If your cat is sick, consult a vet immediately.

Prepare A Place For Childbirth
About two weeks before giving birth, the cat will enter nesting or nesting. This is done to avoid predators, other animals, or alien humans that can disturb their babies. The mother cat has the instinct to protect her cubs from harm.
Usually, cats choose an inadequate place, therefore we are advised to provide alternatives such as cardboard filled with used newspaper and coated with a towel or cloth that can be cleaned and washed.
Put a pillow or towel clean to make your cat feel more comfortable. Also, place food places and sandboxes nearby to make it easier for cats.

Can The Pregnancy Conception Calculator Be Wrong
Yes, of course. So, when does conception happen? There is no possibility being 100 % sure about it. You may be a little bit more certain if you track your cycle and have it perfectly regular. But even ultrasounds and blood tests aren’t faultless. Remember, that your fertile window begins up to 5 days before ovulation and ends one day after it. So, although your conception date is, e.g., 11 July 2019, the intercourse that caused the pregnancy may have occurred as early as 6 July. However, with our conception calendar calculator, you can make an estimated guess!

What Is The Ultrasound Date And Why Is It Different From My Due Date
When a doctor performs an ultrasound, they write a report on the findings and include two estimated due dates. The first date is calculated using the date of the LMP. The second date is based on the ultrasound measurements. These dates are rarely the same.
When your doctor evaluates the ultrasound results, theyll determine whether or not these dates are in agreement. Your doctor probably wont change your due date unless its significantly different from your ultrasound date.
If you have more ultrasounds, each ultrasound report will contain a new due date based on the most recent measurements. An expected due date shouldnt be changed based on measurements from a second- or third-trimester ultrasound.
Due date estimations are more accurate earlier in pregnancy. Later ultrasounds are helpful in determining whether the fetus is growing well but not for determining the age of the fetus.
How Soon Can You Find Out Your Babys Sex
The formation of the vulva or penis starts occurring by the 6th week of pregnancy. Female and male fetuses look quite similar during the first-trimester ultrasound until about the 14th week of pregnancy.
There is a theory, called the Ramzi theory, that suggests that you can predict the sex of a fetus by as early as the 6th week of pregnancy by looking at the placement of the placenta on an ultrasound image. The theory says that its possible to tell the sex of a fetus by checking which side of the uterus the fetus is on. Nevertheless, theres no scientific evidence to support this method.
You can also find out the sex of your baby by having noninvasive prenatal testing , a blood test, which is usually done between 11 and 14 weeks of pregnancy.
Genetic testing methods such as amniocentesis or chorionic villus sampling can also reveal the sex of your baby. Health care providers generally perform CVS between the 11th and 14th weeks of pregnancy and amniocentesis, between the 15th and 20th weeks. These tests are primarily done when the health care provider suspects fetal abnormalities, and the tests pose certain risks. Experts dont recommend these tests only to determine the sex of the fetus.
The first-trimester screening is usually done between weeks 11 and 14.
There are two steps to this screening: a blood test and an ultrasound scan.

What If Your Lmp Due Date And Ultrasound Due Dates Arent The Same
What if your due date is different than the due date according to the ultrasound? Or what if you have four different due dates?! , ovulation, and ultrasound.)
In these instances, your OB or midwife may adjust your due according to the ultrasound, since a dating scan is considered more accurate.
Note: Many healthcare providers may not adjust the due date unless youre more than a week off, but this can have implications at the end of pregnancy in terms of induction. If you feel like your due date needs to be adjusted, ask for a dating ultrasound or follow up with your doctor to adjust your due date. If your due date is not adjusted, you may hear talk about inductions when youre one week late, even if that could actually be your true due date.
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.
