How Does the Baby Genie Pregnancy Due Date Predictor and Weekly Pregnancy Calendar Work?

The Baby Genie Pregnancy Due Date Predictor and Weekly Pregnancy Calendar can help you predict your possible due date as well as get an idea of what stage your baby may be in development during each week of your pregnancy. The majority of pregnancies will last around 40 weeks (38 weeks from actual conception) and so our calculator helps you estimate the time between the start of your last menstrual period and your possible expected due date. Your due date is typically calculated by subtracting 3 months from the 1st day of your last menstrual period, or LMP, and then adding 7 days to that number (assuming a 28 day cycle). The LMP or last menstrual period is the time of your regular bleeding. The 1st day of the LMP is the day your menstrual cycle started and that is the date you enter when entering the LMP in our due date calculator. Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. This is also how many doctors will estimate your due date and it is usually a fairly accurate estimate however it is also very normal for some women to deliver their baby a week or two after or before their expected due date. In fact, based on many studies, only around 5% babies are actually born on their actual expected due date!

For the most accurate estimate of your expected due date it is best to seek advice from your doctor or medical professional as they can best help you to accurately determine your due date based on their knowledge of your more complete medical conditions. Your doctor can also run more in depth tests to determine a more exact due date estimate including monitoring the size of your uterus or fundal height (the top of your uterus), early ultrasound pictures, or by following the stages of pregnancy milestones such as the first heartbeat (usually around 9 to 12 weeks of pregnancy) or when you start feeling the baby move which typically occurs around 16 to 22 weeks of pregnancy. When you use our free calculator we also will provide you with a handy week by week pregnancy calendar that will help you know more about each week of a typical pregnancy and the stages of development your baby may be in.

Please note that the Baby Genie Pregnancy Due Date Calculator and weekly pregnancy calendar should only be used as estimates and should not be taken as any form of actual medical advice. Every pregnancy is unique and your baby will come when it is ready. Be sure to talk to your health care provider about your due date. Calculation of an accurate pregnancy due date is among the most important steps in pregnancy and proper prenatal care is a very important step in growing a healthy baby. If you think you are pregnant or have a positive home pregnancy test then do not delay, call your doctor to schedule your first prenatal appointment today!
