## Video: How To Calculate Your Pregnancy Calendar

As soon as a woman finds out that she will soon become a mother, she immediately has many questions. When the due date comes, how to eat and what lifestyle to lead in each week of pregnancy, what happens to the baby at one time or another - these questions come to minds of expectant mothers every day. To answer these questions, there are online services designed to compile and maintain your own pregnancy calendar.

## Instructions

### Step 1

Choose a service convenient for you on the Internet for maintaining an interactive pregnancy calendar. There are many offers, choose from those that you like best. In addition to calculating the timing of childbirth, maternity leave and other parameters in such a calendar, you can find out what is happening with the baby at a given time and see how he looks. Of course, this is conditional, because you can really look at a child only on an ultrasound examination. But all the same, it is important to have at least a general idea.

### Step 2

In the selected service, you will need to fill in your individual data. Enter three parameters: the first day of the last period, the duration of the entire cycle, and the duration of the second phase. This data is entered to determine the date of conception, on the basis of which your pregnancy calendar will be calculated.

### Step 3

Calculate the average cycle time for the last three months. To do this, add up three cycles, from the day of the onset of menstruation to the first day of the next, and divide by 3. The average duration of the second phase is calculated from the moment of ovulation to the onset of menstruation. It usually lasts 2 weeks, but there are exceptions. In this case, calculate based on data from ovulatory tests, basal temperature measurements or ultrasound examination results.

### Step 4

After entering all the data, the program will form your personal pregnancy calendar. It is presented in the form of weekly pages on which you will find all the information of interest about the growth and development of the child. The calendar will tell you when you need to undergo a standard examination, what features of well-being await you at a given stage of pregnancy, what signs to pay attention to, etc. With the help of it, learn how to eat and what lifestyle to lead. In other words, the pregnancy calendar will help you find answers to most of your questions.
