Pregnancy calculator, how it works

Most women don’t know the exact date of conception, but they are usually aware of the beginning of their last menstrual period. This is the point from which a pregnancy is dated. A due date is important in pregnancy because it helps your doctor determine when to perform certain tests or procedures. Hence the need for a pregnancy week calculator by due date. The pregnancy calculator due date is important because the due date helps estimate your baby’s growth and may indicate whether you are overdue. For most women, the fertile time of the month (ovulation) is around the middle of their monthly cycle or about two weeks before the beginning of their next menstrual period. This is all a bit confusing, so using a pregnancy calculator helps in this regard.

How to calculate your due date

Pregnancy lasts about 280 days, or 40 weeks, from the beginning of the last menstrual period. You can calculate your due date by counting 280 days from the first day of bleeding of your last period. A pregnancy calculator helps, but you can also count back 3 months from the date of your last period and add 7 days.The pregnancy due date calculator is easy, but it’s good to know how to manually calculate your due date  Where were we? Yes, You can calculate your due date by counting 280 days from the first day of bleeding of your last period. This also gives you the approximate date of delivery.  As you can see, a pregnancy week calculator by due date helps in all the figuring. For example, if your last period began on February 20th due date is November 27th. Calculating a pregnancy this way gives the gestational age (menstruall age) this is how most doctors and nurses keep track of time during pregnancy. It is different from the ovulatory age (Fertilization age) Fertilization age is two weeks shorter and dates from the actual date of conception. That’s why a pregnancy calculator is beneficial.

Pregnancy due week

Some medical experts are now suggesting that instead of a due date, we use a “due week”, a 7-Day window of time during which delivery might occur. This time would fall between 39 and 1/2 to 40 and 1/2 Weeks. Because so few women (average of 5%) deliver on their actual due date, this 7-Day window could conceivably help ease anxiety about when baby will be born. As you can see, a pregnancy week calculator by due date saves a lot of worries! Many people count the time during pregnancy using weeks. it’s really the easiest way. But it can be confusing to remember to begin counting from when your period starts and that you don’t become pregnant until about 2 weeks later. Using a pregnancy calculator helps in this regard.For example, if your doctor says you were 10 weeks pregnant from your last period, conception occurred 8 weeks ago.

Pregnancy trimesters

You may hear references to your stage of pregnancy by trimester. Trimesters divided pregnancy into three periods each about 13 weeks long. This helps group together developmental stages of the baby during pregnancy. For example your baby’s body structure is largely formed and his or her organ systems during the first trimester.The pregnancy week calculator by due date does not indicate trimesters, but just think in terms of how many weeks pregnant.  Trimesters are three periods, each about 13 weeks. Most miscarriages occur during the first trimester. During the third trimester most maternal problems with pregnancy induced hypertension or pre-eclampsia occur. You may even hear about lunar months referring to a complete cycle of the moon which is 28 days. pregnancy is 280 days from the beginning of your period to your, pregnancy lasts 10 lunar months. Our pregnancy calculator does not figure lunar months. The pregnancy due date calculator is easier, but now we have also shown you how to calculate your due date.
