The Pregnancy Calculator is an online tool that helps women estimate their due date based on their last menstrual period and average menstrual cycle length. This tool is very useful for women to follow the baby's development during pregnancy and prepare for childbirth. The calculator also shows how many weeks pregnant the woman is already, in addition to showing the day of conception.

How to use the Pregnancy Calculator?
To use the pregnancy calculator, follow these steps:
- Determine the date of the last menstruation: The first information you need to provide is the date of the first day of your last period. This is important because the last menstrual period is used to calculate the due date.
- Determine the average length of the menstrual cycle: The second piece of information you need to provide is the average length of your menstrual cycle. This means the number of days that elapse between the first day of one menstrual cycle and the first day of the next menstrual cycle. The average length of the menstrual cycle can vary from woman to woman, but is generally 28 days.
- Enter information into the pregnancy calculator: Now that you have your last period date and average menstrual cycle length, it's time to enter them into the pregnancy calculator. This can be done using an online calculator or spreadsheet, which are freely available on the internet.
- Get your expected due date: After entering the information into the pregnancy calculator, you will be given an expected due date. This date is a rough estimate of the day your baby is due and can help you plan and prepare for your baby's arrival.
- Day of conception and gestational age: In addition to calculating the possible due date, our calculator also estimates a due date and also how many weeks pregnant the person already is.
It is important to remember that the due date is only an estimate and that the baby could be born before or after this date. Furthermore, the pregnancy calculator should not replace medical advice or regular monitoring by a qualified healthcare professional during pregnancy.
Now that you know how to use the pregnancy calculator, be sure to use it to track your baby's development during pregnancy and prepare for childbirth. Always remember to consult a qualified healthcare professional for proper guidance and support throughout the pregnancy and birth process.

How do I know the average length of the menstrual cycle?
The average length of the menstrual cycle can vary from woman to woman and can be influenced by factors such as age, general health, use of hormonal contraceptives, among others. However, it is common for the average menstrual cycle length to be 28 days, with a range of 21 to 35 days.
One way to determine the average length of your menstrual cycle is to track your cycle for a few months. Write down the day your period starts and the number of days your cycle lasts until your next period starts. After a few months, average these numbers to get an idea of your average menstrual cycle length.
If you have any concerns about your menstrual cycle or have fertility issues, it's important to talk to a doctor for further guidance and proper support.
What other ways to calculate pregnancy?
There are other ways to calculate pregnancy in addition to the pregnancy calculator based on the date of the last period and the average length of the menstrual cycle. Some of these ways include:
- Obstetric ultrasound: obstetric ultrasound is one of the most accurate ways to calculate gestational age and probable delivery date. Ultrasound can be performed at different times during pregnancy and is able to accurately measure the size and development of the fetus.
- Known date of conception: in some cases, the date of conception can be known precisely, as in cases of in vitro fertilization or artificial insemination. In these cases, the gestational age is calculated from the date of conception.
- Biochemical markers: in some cases, blood tests can be used to measure levels of hormones associated with pregnancy, such as beta-hCG and progesterone. Based on these markers, gestational age can be calculated.
- Date of last ovulation: in some cases, the date of the last ovulation can be known based on ovulation tests or specific symptoms. Based on the date of the last ovulation, the gestational age can be estimated.
