What is Pregnancy Calculator?
A pregnancy calculator is an easy-to-use tool that helps expectant mothers estimate their due date and track their pregnancy progress. It works by using the first day of your last menstrual period (LMP) or the date of conception to calculate how far along you are and predict the expected delivery date. Since pregnancy is typically 40 weeks (280 days) long, the calculator follows this standard method to estimate key pregnancy milestones.
This tool is especially useful for women with regular menstrual cycles. However, for those with irregular cycles, an ultrasound scan offers a more accurate due date. Our pregnancy calculators also provide insights into baby growth, important prenatal checkups, and trimester breakdowns, helping mothers stay informed throughout their journey.
While a pregnancy calculator gives a general timeline, every pregnancy is unique, and medical confirmation through an ultrasound is recommended. Always consult a doctor for a more precise assessment and personalized care.
How It Works
LMP-Based Calculation
The calculator adds 280 days (40 weeks) to the first day of your last period, which is the standard length of a full-term pregnancy.
Conception Date-Based Calculation
If you know the exact date of conception, the calculator adds 266 days to estimate the due date.
Why Use a Pregnancy Calculator?
- Estimate Your Due Date – Know when your baby is expected to arrive.
- Track Pregnancy Progress – Determine how far along you are.
- Plan Prenatal Care – Schedule important scans and checkups at the right time.
- Understand Baby’s Growth – Follow developmental milestones week by week.
While a pregnancy calculator provides an estimate, a doctor’s confirmation through ultrasound scans gives the most accurate due date.
When Should You Use a Pregnancy Calculator?
A pregnancy calculator is a very impotent tool. It should be used by all expecting mothers and couples to track their pregnancy and babies growth from the moment they come to know that they are expecting till the time of delivery.

FAQ's
Frequently Asked Questions
Find answers to common pregnancy calculator related questions here.
How accurate is a pregnancy calculator?
A pregnancy calculator provides an estimated due date based on your last menstrual period (LMP) or conception date. However, actual delivery may vary, and ultrasound scans offer the most precise confirmation.
How do I calculate my pregnancy due date?
Most pregnancy calculators add 280 days (40 weeks) to the first day of your last period. If you know the conception date, the calculator adds 266 days to estimate the due date.
Can I use the pregnancy calculator if I have irregular periods?
If your cycles are irregular, the calculator may not be as accurate. An early ultrasound is the best way to determine your due date in such cases. Book an Ultrasound appointment.
When should I see a doctor after using the pregnancy calculator?
If your pregnancy calculator suggests you are pregnant, schedule a visit with a doctor around 6-8 weeks of pregnancy for confirmation and early prenatal care. Click here to book an appointment with Bengaluru’s best Gynaecologist and Obstetrician.
How does the calculator determine my current pregnancy week?
The calculator counts from the first day of your last menstrual period (LMP). For example, if your LMP was 8 weeks ago, you are considered 8 weeks pregnant, even though conception happened about 6 weeks ago.
Can I calculate my pregnancy without knowing my last period date?
Yes, but it’s less precise. You can estimate based on the date of conception if known, or an ultrasound scan can help determine the fetal age.
Can I use a pregnancy calculator if I conceived through IVF?
Yes, but the calculation is different. Your doctor will provide an estimated due date based on the embryo transfer date and IVF treatment details.
Does the pregnancy calculator work for twin or multiple pregnancies?
Yes, but multiple pregnancies often have slightly different gestational timelines, and actual delivery may happen earlier than 40 weeks. Your doctor will monitor your progress closely.
Why does pregnancy last 40 weeks if a baby is conceived about 38 weeks before birth?
Pregnancy is measured from the first day of your last period, not from conception. Since ovulation occurs around two weeks after the period starts, doctors include those two weeks in the pregnancy count.
What if my due date changes after an ultrasound?
Ultrasound scans, especially in early pregnancy, provide a more accurate due date than LMP-based calculations. If the due date differs by more than 7 days, your doctor may adjust it.
Can a pregnancy calculator determine the baby’s gender?
No, the calculator only estimates dates. Determination of babies gender is illegal and banned in India. Determining the babies gender is punishable as per Indian Law.
What should I do after finding out my estimated due date?
Start prenatal care, maintain a healthy lifestyle. Book an appointment with a pregnancy and maternity doctor at Nectar MCH and follow your doctor’s advice to ensure a smooth pregnancy journey.
Can a pregnancy calculator confirm if I’m pregnant?
No, it only estimates your due date based on your LMP or conception date. To confirm pregnancy, take a home pregnancy test or visit a doctor.
How can I book a consultation with a surgeon?
You can book an appointment by:
Calling our hospital reception
Visiting the hospital directly
Scheduling online via our website
How does the pregnancy calculator account for leap years?
The calculator automatically adjusts for leap years, so your estimated due date remains accurate regardless of the extra day in February.
Can lifestyle or health conditions affect my actual due date?
Yes, factors like maternal health, weight, stress levels, and pregnancy complications can influence when you deliver. Your doctor will guide you based on your specific situation.
