Using A Pregnancy Test With A Weeks Indicator
Pregnancy tests scan your body for hCG , a hormone produced only once an embryo has implanted in your uterus . Some of the fancier, more expensive home pregnancy tests have a weeks indicator that also tells how far along you are. But these tests let you know only that youre one to two weeks, two to three weeks or three-plus weeks pregnant . Fortunately, an ultrasound at your doctors appointment can help pinpoint a more specific due date.
Working Out Your Due Date
Once you have confirmed that you are pregnant, you will want to find out when your baby is due to arrive. The average pregnancy is calculated at 282 days from the first day of your last menstrual period.
However babies rarely keep to an exact timetable, so a full-term pregnancy can be anywhere between 37 and 42 weeks. A baby born before 37 weeks is considered to be premature and anything past 42 weeks is considered overdue.
Due dates are usually calculated on your last period instead of the date of conception because of a number of reasons.
- Although the average woman ovulates approximately 2 weeks after her period, the exact time is not always known.
- Once an egg has been released, it can remain fertile for up to 24 hours.
- Sperm can last for up to 5 days after intercourse to fertilise an egg.
If your periods are irregular or you are unsure of the date, an ultrasound will help determine the development of the embryo and your due date. Ultrasound scans can be done at any stage of pregnancy after the first 6 weeks. The best timing for an ultrasound to determine the due date is between 8 weeks and 13 weeks 6 days.
You can use the Pregnancy, Birth and Baby due date calculator to work out when your baby is due.
Some doctors will refer to your due date as ‘expected date of confinement’ or EDC.
Acog Definition Of Pregnancy
- Early-term: 37 weeks through 38 weeks and six days
- Full-term: 39 weeks through 40 weeks and six days
- Late-term: 41 weeks through 41 weeks and six days
- Post-term: any pregnancy that goes beyond 42 weeks
Sometimes, when talking about twins or triplets, you will hear people say things like, Twins are full-term at 37 weeks. But this isnt truly accurate. All pregnanciesincluding twins, triplets, or morearent truly full-term until they reach 39 weeks.
While you might be at greater risk of earlier labor with twins, that doesn’t affect how the timing of labor would be classified.

Why Due Dates Are So Hard To Predict
There are a bunch of reasons as to why its so hard to predict when baby will be born. Lets start with the most basic: Soon-to-be-moms often count nine months ahead, but pregnancy is typically 40 weeks from the first day of your last period, which is, of course, more like 10 months.
Another concept to understand when figuring out due dates is that theres no such thing as a firm date for when baby will actually arrive. Even what your doctor tells you is simply an estimate. After all, every pregnancy is different. Some babies, as if eager to greet you, arrive early others take their time and enter late, on their own terms.
Gauging the size of your bump probably wont help much either. For instance, when it isnt your first pregnancy, your bump may show a bit faster than it did the first time around. The growth in the abdomen is much quicker, says Jessica Shepherd, MD, an ob-gyn and womens health expert. Your abdominal and uterine muscles are looser now, since they stretched during your first pregnancy. Plus, your uterus doesnt return to its original pre-pregnancy size after baby number 1, giving your body a head start. So, youll likely pop earlier.
What Changes Are Occurring With Your Body
Your period has just begun, and you may be thinking about becoming pregnant. Your ovulation time is the most important thing you need to understand when trying to conceive. Ovulation occurs when a mature egg is released from the ovary, pushed down the fallopian tube, and available to be fertilized.
The lining of the uterus has thickened to prepare for a fertilized egg. If conception does not occur, the uterine lining will be shed. The shedding of an unfertilized egg and the uterine wall occurs during menstruation.
There are also several facts that you need to know concerning ovulation:
- An egg lives 12-24 hours after leaving the ovary.
- Normally, only one egg is released each time you ovulate.
- Ovulation can be affected by stress, illness, travel, and significant changes in weight, exercise, and sleeping patterns.
- Some women may experience light spotting during ovulation. This is not considered to be an actual period, but rather an ovulatory bleeding.

How Many Weeks Do You Think It Will Take From Conception To The Estimated Due Date
Pregnancy lasts 40 weeks, beginning with the first day of a womans last menstrual period and ending with the expected due date. Because counting begins around two weeks before the baby is conceived, this way of estimating pregnancy adds two weeks. From conception through the projected due date, a pregnancy lasts 38 weeks.
The procedures described above are accurate within one to five days, but pinpointing the precise day is difficult. This is why doctors base a pregnancy on the date of your last menstrual cycle. They do this for consistency, and if you really want to know when you conceived, you may guess two weeks after your previous period.

How To Count Pregnancy Weeks
The basic formula is LMP + 280 days = EDD , and pregnancy week counting starts on the first day of your last period, starting with Week 0 and counting all the way up to Week 40 and as high as Week 42. Heres another way to think about it: one week after the first day of your last period, youre already considered one week pregnant.
But keep in mind that this formula is based on a 28-day menstrual cycle, which is just the average cycle length. Some people have shorter cycles, some people have longer cycles, and that might affect your due date.
What if you dont remember exactly when the first day of your last period was? If youre not in the habit of tracking your cycle with apps or calendars, dont worry most healthcare providers will perform an ultrasound when youre around seven to eight weeks pregnant to get an early measurement of your baby. The size helps narrow down the amount of time the embryo has been developing. This scan is often taken as the most accurate measurement of your pregnancy weeks, so dont be surprised if your provider has you jump forward or backward a week depending on the size of your baby.

How Do I Calculate My Pregnancy
The first day of your most recent menstruation The most popular method for calculating your due date is to count 40 weeks from the beginning day of your last menstrual cycle . That is how the majority of healthcare providers operate. However, some women don’t become pregnant until their fifth week of pregnancy, while others start showing up as early as their seventh week. There are also methods that use measurements of your fundus or your waist to determine your due date. These methods are less common but can be useful if you want to know exactly when you will give birth rather than just within a range of dates.
It is important to remember that your due date is simply an estimate, and there are factors other than your LMP that can affect how close it comes to predicting what will happen in your womb after conception. For example, if you have a history of preterm labor, then it is possible that you could go into premature labor before your due date even if everything else about your pregnancy was normal. In this case, your doctor might want to monitor you more closely or recommend modifications to your diet or exercise plan before you reach your due date.
Many women worry that if they know their exact due date, then something bad will happen if it isn’t met. But the fact is that many women who deliver before their due date experienceno problems whatsoever.
