Whats In Store For Me Until My Due Date
Now that you know how far along you are, it might be helpful to know that pregnancies are often referred to in weeks and trimesters. Take a look at this pregnancy timeline for a breakdown of the weeks, months, and trimesters of pregnancy:
Here are some of the things you can expect in each trimester of pregnancy:
First trimester : You might notice some early signs of pregnancy, such as morning sickness and food cravings. Your provider will be able to confirm your pregnancy and set up your prenatal visits to make sure you and your baby stay healthy and safe.
Second trimester : This trimester is often referred to as the honeymoon phase of pregnancy. You may feel as if you have some extra energy to get things done, like baby-proofing your home, going to prenatal classes, and doing some gentle pregnancy exercise.
If you aren’t already, this may also be a good time to start doing Kegel exercises to strengthen your pelvic floor muscles. You can do these simple muscle clenches anywhere, and they’re beneficial not only during pregnancy and labor, but afterwards as well.
Third trimester : You’re nearly there! As you get closer to the birth of your baby, you’ll want to get prepared by making sure you have all the right baby gear. But remember to take the opportunity to slow down and rest whenever you can.

Conception Calculator Based On Lmp
The other method of using the pregnancy conception calculator is to provide the first day of your last menstruation and the average length of your menstrual cycle. The majority of cycles last around 28 days. However, typical values range between 21 and 35 days.
In cycles of 28 days, ovulation happens around 14 days before the beginning of the next cycle. So, if a cycle lasts 28 days, ovulation occurs the 14th day after the first day of the cycle . If it’s shorter, you subtract the corresponding number, e.g., for a 22 days cycle – ovulation occurs on the 8th day. If it’s longer, you add some days, e.g., for a 34 day cycle – ovulation is on the 20th day. For cycles longer than 35 days or shorter than 21 days, these calculations are not applicable and you should consult by a doctor. If you’re not sure how long your cycles are, leave the default number of 28 days.
When does conception happen? How long does conception take? The fertile window begins 3-5 days before the ovulation date, and ends one day after it. It means, to get pregnant, you should have intercourse within this time. Although sperm can survive up to 7 days inside a woman’s body, conception does not happen until ovulation. Therefore, conception day is the day of ovulation and might last for 24 hours after the egg is release. Therefore, the formula to estimate the conception date based on the LMP:
LMP + cycle length – 14 = conception date
How Do I Calculate My Due Date
You can calculate your due date by using:
The date of your last period
You can calculate your due date if you know the first day of your last menstrual period before you got pregnant. Your due date is 40 weeks after the day you started your last period.
This method is a good way to estimate when your baby is due because many women remember the day they started their period. But it might not always be accurate, especially if you have an irregular menstrual cycle or are on birth control.
The date you conceived
If you know the exact day you conceived, you can use that information to figure out when your baby is due. Count ahead 38 weeks from the day you got pregnant. That day is your due date.
This method is only accurate if youre sure about the day you got pregnant. You may only know the specific day you got pregnant if you know when you ovulated. Ovulation happens when your ovaries release an egg. Usually, women ovulate about 14 days after the first day of their period. You can track your ovulation by:
- Taking your basal body temperature around the time when you think you might be ovulating.
- Tracking your ovulation symptoms, such as ovulation pain and cervical mucus.
- Using an ovulation predictor kit. These kits use your urine to detect when youre ovulating.

What If I Have Irregular Periods Or Long Cycles
Some women have cycles that are consistently longer than the average 28-day cycle. In these cases, a pregnancy wheel can still be used, but some simple calculations are necessary.
The second half of a womans menstrual cycle always lasts for 14 days. This is the time from ovulation to the next menstrual period. If your cycle is 35 days long, for example, then you probably ovulated on day 21.
Once you have a general idea of when you ovulated, you can use an adjusted LMP to find your due date with a pregnancy wheel.
For example, if your menstrual cycle is usually 35 days long and the first day of your LMP was November 1:
After you calculate your adjusted LMP date, simply mark it on the pregnancy wheel and then look at the date where the line crosses. That is your estimated due date.
Some pregnancy wheels may allow you to enter the date of conception which occurs within 72 hours of ovulation instead of the date of your LMP.
What Is My Due Date
Your due date, also known as your estimated date of delivery, is the approximate date your labor might begin. Your estimated due date is commonly calculated by adding 280 days to the date of the first day of your last period, using Naegeles rule.1This may vary if you have irregular periods.
It’s worth noting that although predicted due dates are commonly calculated at 280 days, a baby is born on its predicted due date just 5% of the time.2 A 2020 study published in the International Journal of Obstetrics & Gynaecology suggests a number of factors that can influence the length of your pregnancy, including ethnicity, height, variations in the menstrual cycle, the timing of ovulation, parity and maternal weight. It is for this reason that calculations using Naegeles rule can be considered as an estimate and not a definitive date.3

As well as the specific week of your Pregnancy, the Pregnancy Weeks Calculator will also provide your approximate Due Date.

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!

First Day Of Last Period
Most pregnancies last around 40 weeks , so typically the best way to estimate your due date is to count 40 weeks, or 280 days, from the first day of your last menstrual period . You could also subtract three months from the first day of your last period and add seven days.
The first day of your LMP is how most health care providers estimate a baby’s due date. But remember, it’s only an estimated due date, not a deadline for your baby to arrive. Just 4 percent of babies are born on their estimated due date.

Practical Example Of The Use Of Conception Date Calculator
Let’s take Anne. She is 11 weeks pregnant, and still doesn’t know her conception day. The first day of her last period was 11 June 2018, and typically, her cycle lasts for 31 days . As mentioned before, we can assume that her ovulation began around 17 days after her LMP, on 28 June 2018.
11th June 2018 + 17 days = 28th June 2018
She conceived around her ovulation date , on 28 June 2018. However, instead of all this counting, she used our pregnancy conception calculator.
Next up is Maggie. She just came back from the doctor, who told her that the due date is on 19 September 2019. Now, she has one question: ‘what day did I conceive?’.
19th September 2019 – 266 days = 26th January 2019
You don’t have to do the calculations by hand! Just put the numbers into our conception date calculator based on the due date. It can also work as a pregnancy week calculator, giving you an estimated week of pregnancy and the first day of your last period.
Now, to ensure that both the mother and child are healthy during and after pregnancy, both Anne and Maggie should control their pregnancy weight gain.

How Are The Weeks Of Pregnancy Calculated
The 40 weeks of pregnancy begin on the first day of your last menstrual period.
This can be a little confusing because, for most people, conception doesnt occur until day 14 of the menstrual cycle. So yes, you arent actually pregnant during those first two weeks of pregnancy.
Modern data suggests that women have their babies a few days after their due date on average. Studies like this one found that Naegeles rule consistently places the due date about 2-4 days too early. So a better estimate may be 40 weeks and 3 days from LMP.
Alternatively, you can use our Advanced Due Date Calculator, which uses the Mittendorf-Williams rule to calculate your due date, which has been shown to be more accurate.
How To Calculate In Weeks
To calculate how many weeks you are, start by taking note of the first day of your last period on a calendar, or your LMD . Every 7 days from that first day counts as 1 week in your pregnancy.
For example, if the first day of the last period was March 11 and you recently had a positive pregnancy test, your first day of pregnancy is March 11 . If March 11 was day 1, then March 18 will mark week 1 of your pregnancy. April 16, for example is calculated as 1 week and 1 day of your pregnancy, and you will have been in your second month.
Calculation is done this way because the exact fertilization day is difficult to determine. Sperm cells can survive in the woman’s body for up to 7 days, and can fertilize the egg and initiate the pregnancy on any of these days.

Can My Due Date Change
During your prenatal checkups, your healthcare provider will monitor how far along you are. Don’t be surprised, though, if your provider gives you a slightly different due date than the one you calculated.
Also, most babies don’t arrive exactly on their due date. Every pregnancy is unique, and only a small percentage of babies are born right on time. Babies are typically born between weeks 38 and 42, and it’s totally normal for your baby to arrive any time during this window.
If your baby is born pre-term, your doctor will be able to advise you on any extra care your baby might need. On the other hand, if your baby isn’t born by the end of week 42, your doctor may suggest inducing the labor to bring on a vaginal birth, or he may discuss the option of a cesarean section with you.
