Pregnancy calculators compute the due date and current week of pregnancy based on either the date of the last period or the date of conception. CalcMate's pregnancy calculator yields consistent, precise results that show the pregnancy timeline, weeks, and trimesters, based on medical standards.
To track your progress, please enter the date of your last period or your due date into the pregnancy calculator. It calculates the current week and trimester to help determine the stage you're in, be it 6 weeks or 8 months pregnant.
Input the date of the last menstrual period or the date of conception into the pregnancy due date calculator. This tool will calculate the due date and how far along you are in weeks using a 40-week pregnancy cycle.
Your due date can be input into the pregnancy calculator which will determine the current week you are on. The calculator will calculate the difference between your due date and today's date to give you weeks and days pregnant estimating the level of clarity in pregnancy.
Tracking pregnancy week by week involves monitoring important fetal growth milestones. With the last period or conception date, the calculator provides the necessary details including the current week, trimester as well as vital stages like 5 or 6 months pregnant.
The Pregnancy Calculator finds the due date based on Naegele’s Rule which states to first take the LMP and add 280 days (40 weeks), then adjust by subtracting 3 months and adding 7 days, and tracks weeks pregnant by calculating the difference from the conception date or LMP. This method is recognized by the American College of Obstetricians and Gynecologists (ACOG).
The calculator uses a singleton pregnancy with a length of 40 weeks. For twins or multiples, the due date may be sooner than average; typically the gestation for twins is 37-38 weeks. Check with your obstetrician for an accurate timeline for multiple births.
The due date (280 days from the last menstrual period) is a prediction based upon Naegele's Rule; in fact only 4 % of babies are born on their due date. Early ultrasounds are more accurate predictions so check with your health professional if available.
