The other method of using the pregnancy conception calculator is to provide the first day of your last menstruation (LMP) and the average length of your menstrual cycle. Let's go back to the question: what day did I conceive? In our conception calculator, we subtract 266 days from the estimated due date and get the most probable day of conception: But don't worry if the due date changes or you go into labor on a different date - only 4% of babies are born on their due date, and 80% are born either two weeks before or after the date. If a baby is born before week 37, it's called premature birth. That is 266 days from the conception date. Pregnancy typically lasts around 40 weeks (counted from the first day of your last period). Remember that those dates, as well as the conception calendar, are only an estimation and may change during the next visit. Although the doctor can see the baby from the 5-6th week of pregnancy, the best time to go for the first sonography is between weeks 8 and 12.īased on the characteristics of the image and the results of your [blood test, compared with hCG levels calculator, the due date and week of pregnancy can be determined.
