What Is a Pregnancy Calculator?
A pregnancy calculator (also called a due date calculator or gestational age calculator) is a tool that estimates how far along your pregnancy is, your expected baby’s due date, and important pregnancy milestones based on standard obstetric timelines (typically 40 weeks).
You can calculate using:
-
LMP (most common)
-
Ultrasound results (more accurate in early pregnancy)
-
Conception date (if known)
- IVF Embryo Transfer
Our tool works as a pregnancy week calculator, a trimester calculator, and a due date estimator – all in one.
Why Knowing Your Due Date Matters
Your estimated due date is more than just a single day on the calendar. It’s a guide that helps healthcare providers track your baby’s growth, schedule important appointments and tests, and allows you to plan for the arrival of your little one. While only a small percentage of babies are born exactly on their due date, it provides a valuable timeframe for your pregnancy journey.

Understanding Pregnancy Trimesters
Pregnancy is typically divided into three trimesters, each marked by unique developments for both mother and baby:
- First Trimester (Weeks 1-13): This is a period of rapid development. The embryo forms vital organs, and you might experience early pregnancy symptoms like morning sickness and fatigue.
- Second Trimester (Weeks 14-27): Often called the “golden trimester,” many uncomfortable early symptoms subside. You’ll likely feel your baby’s first movements (quickening), and your baby will grow significantly.
- Third Trimester (Weeks 28-40+): The final stretch! Your baby continues to grow and mature, gaining weight and preparing for birth. You’ll likely experience more physical changes as your body gets ready for labor.
For comprehensive global health guidelines and information on pregnancy and childbirth, you can refer to resources from the World Health Organization (WHO).
Common Pregnancy Misconceptions Debunked
There’s a lot of information (and misinformation!) out there about pregnancy. Here are a few common myths we’d like to clarify:
- Myth: You should “eat for two.”
- Fact: While your nutritional needs increase, you don’t need to double your food intake. Focus on nutrient-dense foods and listen to your body’s cues. Most women only need an additional 300-450 calories per day in the second and third trimesters.
- Myth: Due dates are exact.
- Fact: Only about 5% of babies are born on their estimated due date. Most full-term pregnancies occur within two weeks before or after the EDD. Think of it as a target window, not a fixed appointment!
- Myth: Morning sickness only happens in the morning.
- Fact: Nausea and vomiting during pregnancy can occur at any time of day or night and is a common symptom of hormonal changes.
Frequently Asked Questions (FAQ)
LMP stands for "Last Menstrual Period." It refers to the first day of your last menstrual period. Most due date calculators use this date as the starting point for calculating your estimated due date, assuming a 28-day menstrual cycle.
If you don't know your LMP, an early ultrasound will be the most reliable way for your healthcare provider to determine your due date. If you know your approximate conception date, some calculators (like ours) can use that too, but ultrasound remains the gold standard in this scenario.
Yes! You can switch to the ultrasound method and input your gestational age and ultrasound date to calculate your pregnancy status.
Yes, your due date can sometimes change. While an initial due date is set, usually based on your LMP, it might be adjusted after an early ultrasound. Ultrasounds in the first trimester are very accurate for dating a pregnancy, and your doctor might adjust the due date if it significantly differs from the LMP estimate.
This version is designed for singleton pregnancies, but an IVF-specific version is coming soon!
A pregnancy is considered full-term between 39 weeks 0 days and 40 weeks 6 days. Babies born before 37 weeks are considered preterm, and those born between 37 weeks 0 days and 38 weeks 6 days are considered early term.
A typical human pregnancy lasts approximately 40 weeks (280 days) from the first day of the last menstrual period, or about 38 weeks from the date of conception. This is divided into three trimesters.
No, your due date is just an estimate. Only about 5% of babies are born exactly on their due date. Most full-term babies arrive within two weeks before or after their estimated due date.
Pregnancy is divided into three trimesters: * First Trimester: Weeks 1 through 13 * Second Trimester: Weeks 14 through 27 * Third Trimester: Weeks 28 through the end of pregnancy (around week 40)
While a standard due date calculation assumes a 28-day cycle, providing your average cycle length allows the calculator to make a more accurate adjustment. If your cycle is longer or shorter than 28 days, it can impact your ovulation and conception dates, and thus your estimated due date.
While chronic stress can impact overall health and potentially influence pregnancy outcomes, it generally does not directly change your estimated due date. Your due date is calculated based on physiological markers (LMP, conception, ultrasound measurements), not external factors like stress.
Pregnancy due date calculators provide an estimated due date (EDD) based on standard formulas. While helpful, they offer an estimate. Factors like irregular cycles or unknown conception dates can affect accuracy. An ultrasound in early pregnancy is often considered the most accurate way to confirm a due date.
