Discover Some Different Ways You Can Predict Your Baby Due Date

All pregnant women want to know what day they are due, and there are several ways to find out how to predict your baby due date. The estimated due date, or EDD, is an essential day to keep in mind. It can let you know if your pregnancy is progressing correctly, and how your baby is developing. Knowing the age of the fetus is the key to finding out your EDD.

Your menstrual cycle is your first indication of the EDD of your baby. If you know when your last period started, all you do is subtract seven days from it, then three months back, and you will have the EDD. For example, if you are due on June twenty seventh, you subtract seven days, which would be June twentieth, then go back three months, leaving you with a EDD of March twentieth.

The count back method based of your period is from Naegele’s rule, which defines a full term pregnancy as being forty weeks. It is possible to fine tune your EDD based on additional factors, such as your age, how many times you have carried to full term, your race, age, and how regular and long your menstrual cycle is.

If you know when you got pregnant, the day of conception, this is another, more accurate way of knowing your EDD. You take the date of conception, and add thirty eight weeks to it. This method is accurate because there is only a limited amount of time that sperm is viable once ejaculated, but isn’t used very often because most women don’t keep a record of their sex lives.

Your hormonal levels also give you a clue to your EDD. Your doctor, at your first prenatal visit, will have you take a pee test that will analyze the B-hcG hormone levels in your urine. If your level is around 100,000, you have been pregnant for about ten weeks. Depending on the level, your doctor will let you know when to expect your little one.

More accurate than the last menstrual cycle, conception date, or hormone levels is a ultra sound dating. Through the sonogram, the ultra sound technician is able to judge the age of the fetus based on measurements of the uterus, gestational sac, he crown to rump measurement of the fetus, or by the circumference of the baby’s head. As the pregnancy progresses, it becomes harder to find an accurate EDD, so it’s important to have an ultra sound early in the pregnancy.

The window that a full-term birth can occur is between thirty seven to forty two weeks along. The EDD is just one day in a period of five weeks, and even if you have all the information necessary to determine your EDD, there is only a five percent chance you will give birth on that day.

The methods into finding out how to predict your baby due date aren’t hard to do. You can do simple math, take a urine test, or have an expert measure your baby for you through the ultra sound. However, you need to understand the EDD is only a general day you could deliver, and you should be prepared to have your baby within the week prior to the EDD and the week after it, which is when fifty percent of all births occur.
