How to Use Our “How Many Weeks Pregnant” Calculator
I designed this calculator to be as simple as possible because, let’s be honest, pregnancy brain is real! Here’s how to get your accurate results in just three easy steps:
Enter Your Last Menstrual Period Date
Select the first day your last period started (not when it ended). This is the foundation for calculating “how many weeks am I pregnant from my last period.” Don’t worry if you can’t remember the exact date – an approximation will still give you valuable information.
Choose Your Average Cycle Length
Select your typical cycle length from the dropdown. While 28 days is average, cycles between 21-35 days are completely normal. This helps our calculator give you the most accurate answer to “when did I conceive and how many weeks am I?”
Get Your Complete Pregnancy Timeline
Click calculate to instantly receive your current pregnancy week, due date, conception date, and pregnancy percentage. You’ll have all the information you need to plan your beautiful journey ahead!
The Science Behind “How Many Weeks Pregnant Am I?”
Understanding the Calculation
Our how many weeks pregnant calculator uses the medically accepted Naegele’s Rule, which adds 280 days (40 weeks) to the first day of your last menstrual period. This method assumes conception occurs around day 14 of a 28-day cycle.
However, I know every woman’s cycle is different! That’s why our calculator adjusts for your specific cycle length, giving you a more personalized answer when you ask “how many weeks am I pregnant.” The actual gestation period from conception is about 266 days (38 weeks).
