This due date calculator will be helpful for you when it comes to estimating your due date depending on the personal biological cycles you have.
Even though pregnancy starts when you actually conceive, you should estimate your due date from 1st day of your previous menstrual period. Starting from there, usually pregnancy lasts for anywhere between 37 to 42 weeks, and due date is around 40 weeks to 38 weeks after your conception. If you talk about 40 weeks, it is almost 9 months and 6 days. If you take it in lunar months then it is 10 months.
If you want to know how is the due date calculated, before actually using this due date calculator, the calculation is done by simply adding two hundred and eighty days, which amounts to 40 weeks, to first day of the last menstrual period you had. It also works on the assumption that you have 28 days cycle.
Also, keep it in mind that the menstrual period as well as the ovulation is considered as initial couple of weeks of your pregnancy. If the delivery happens on the estimated due date then your baby will be just 38 weeks of age when born rather than 40 weeks.
It is also important to keep in mind that due dates are just the estimates. All the pregnancies are unique and the baby comes out as soon as it is ready. So, it is always advisable that you talk to the health care practitioner you've been consulting before completely relying on any due dates that you can calculate with different formulas available out there.
An average of 5 percent of total births happen exactly on due dates that have been estimated using a due date calculator or different formulas for the calculation of due dates available today. Most of the deliveries happen inside a week before or after the due date that is estimated through different means. The duration for a normal pregnancy is somewhere between 38 to 42 weeks. So, you should keep all these things in mind when considering due date estimations.
Almost every due date report obtained through conventional means contains the following information.
. Probable due date
. Date of conception
. Baby status including size, weight and heartbeat
. The due dates for the multiples (twins for instance)
. Trimester stages
. Timeline for any major milestones in the Embryo/Fetal development
. Dates for prenatal testing
. Fun facts about due dates
A sonograph at an early stage can determine exactly for how long you have been pregnant. And, it does that quite accurately as well. Typically, doctors express pregnancy age i.e. age of the embryo according to your menstrual date depending on 1st day of your last menstrual cycle.
Just like the ovulation calculator, this due date calculator is also very simple and easy to use. You just need to provide two input values here as well. The calculator gives you a date format where you have to select the date when your last menstrual period started. Then there is another list for the number of days you usually have in your menstrual period. You can select any number from 20 to 45 while the default value is 28 which is the normal case with most of the women.
Once you have entered the required values, it's time to hit the calculate button and the calculator will show you the expected due date for your delivery. If you are able to conceive in the normal timeframe according to the information that you have provided then the due date shown to you is probably when your delivery will happen.
So, use this due date calculator for estimating your due date but make sure that you continue to see your doctor regularly and rely on their observations for when you're due.
