When you go to the doctor and ask about calculating your due date, they will tell you that there is no formula that is 100% accurate. Although this stands out as the first question most couples ask, the technology hasn’t evolved far enough yet.

In most cases, a full term will be around 40 weeks, but variations do occur due to many different factors. Before we talk about them, we need to focus on how you can calculate your due date when signs of pregnancy appear.

Online and offline pregnancy calculators

The great news for all couples is the fact that there are online and offline pregnancy calculators. The offline ones will be available in pharmacies and in the gynecologist’s offices. Online ones are available on many different websites. Both use the same way to calculate your expiration date and will take into account:

1. The date your last menstrual period began.

2. The date of conception, which is optional since not many people know about it.

3. The length of the woman’s regular menstrual cycle. Most women will have one in 28 days, but differences may appear.

What can trigger the birth before the due date?

Although today you can calculate your due date and get pretty close to it, there are some factors that will have a negative impact on your signs of pregnancy and end up with a premature delivery. The full term of a pregnancy is 37 weeks and if the baby is born too early, she faces preterm labor. A doctor will tell you that several factors can cause this, such as:

• Unhealthy eating habits.
• cervical incompetence
• Nutrition

What causes a late labor?

Most women will give birth after 37 weeks. In most cases, labor occurs between 38 and 42 weeks, but this is not always the case. In most situations, the new mother will have the baby after her due date. The problem is that a pregnancy that exceeds 42 weeks is dangerous. In this case it can end with perinatal death. A doctor will monitor this and offer solutions if the pregnancy exceeds this period.

Due dates are very important for any woman. This is because they allow them to do a couple of things. For starters, they can plan everything accordingly and be ready when the time comes. Second, the mom-to-be will always know when she needs to go to the doctor for an ultrasound. Unfortunately, there are some women who are not taking it into account. You shouldn’t be one of them.

Make sure you are going to use a pregnancy due date calculator. We recommend that you use online calculators because they can be used in the comfort of your home and will not cost you anything. This is very useful for many pregnant mothers.
