In the event that you realize you’re pregnant, you probably would want to be the first to know when your child will arrive. The pregnancy due date calculator can help you to figure your pregnancy due date.
How is the Due-date Calculated?
The due date is calculated by adding 40 weeks (or 280 days) to the first day of your last menstrual period (LMP).
This is the same calculation that your midwife and healthcare professional will use as well.
This method is based on the assumption that women ovulate for about 2 weeks after the commencement of their period and pregnancy typically lasts for about 38 weeks from conception.
In addition, it is way easier to remember the beginning of your period than the day you conceived.
If the average length of your menstrual cycle is 28 days, it means that your menstrual cycle actually begins around two weeks before you can conceive.
This is why it is said that pregnancies last 40 weeks, instead of 38 weeks.
Estimating the due date of your pregnancy is a significant part of your prenatal care but there are no guarantees.
Delivering your baby a week or two, before or after your due date is normal, however.
How to use the Due-date Calculator
Because you may not know exactly when you conceived, your estimated due date will typically be calculated based on your last menstrual period (LMP).
The pregnancy due-date calculator uses a simple approach to determine the due date.
Simply pick the day of the first day of your last cycle on the pregnancy calculator and press send to find your due date.
That is it!
The calculator will do the rest.
You will then receive your estimated due date.
What do I do After I Have Calculated my Due Date?
Once you’ve calculated your pregnancy due date, you can get a better idea of when to expect your little one and start planning accordingly.
If you haven’t already done so, one of the first steps you should take is to schedule an appointment with your doctor, to confirm that you’re pregnant.
You will be examined at each of the following prenatal care appointments to determine the size of your uterus and monitor the development of your little one.
An exciting part of these check-ups will be pregnancy milestones such as hearing your baby’s heartbeat the first time and seeing your baby when you have an ultrasound.
Along the way, the pregnancy due date may change according to what is found.
Your doctor will be able to advise you best on what to do..
Can the Due Date Change?
It normally doesn’t happen much but it depends on how the due date is first calculated.
It really doesn’t matter if the pregnancy due date changes and the gestation period is off by one or two weeks.
It could only mean you might have an irregular menstrual cycle.
How Accurate is the Due-date Calculator?
The birth calculator measures the due date by adding 40 weeks to the first day of your last menstruation cycle.
If your cycle is consistently shorter, longer, or irregular or cycles than 28 days this calculation method may still be more accurate than other due date calculation methods.
How Likely am I to Give Birth on my Due Date?
An estimate of the due date is still provisional, whether from the calculator, from your doctor or your midwife.
In the two weeks before or after, you are just as likely to go into labor as on your estimated due date.
The main benefit of knowing your due date is that it helps you have everything in place in a good time before your baby’s arrival.
Due date is a simple term and only 5% of pregnancies occur on the due date, with the majority born two weeks before or after.
Pregnancy only counts when ovulation occurs after the last menstrual cycle, i.e. when you technically become pregnant.
It is important to understand that the calculator you are using can only offer you an estimate and the chances of you delivering on that exact date are slim.
It is a simple tool that helps you to determine your approximate due date so that you can get a clearer answer to how far you are.
Why should you calculate my due date?
After confirming you are pregnant, the next thing you will want to know is when your baby is ready to meet you.
Rather than trying to calculate this important date by counting on your fingers, marking your calendar or subtracting and adding weeks and crossing days, you can use the OhBaby’s due-date calculator to calculate your estimated due and begin your countdown to seeing your baby.
Can you plan your due date?
Whether you’re trying to avoid getting pregnant in the middle of the summer or you’re a teacher who wants to maximize your time off when your little one arrives, you can try to plan your due date retrospectively.
However, even if you’re one of the few fortunate ones who can get pregnant whenever they want to, it is tougher to map exactly when you’re going to give birth.
