One and Two Weeks Pregnant<\/h2>\n

Congratulations! During the first and second week of pregnancy your body is preparing for possible conception.<\/p>\n

How is pregnancy calculated?<\/h3>\n

Calculating the day your baby begins to develop and keeping track of your pregnancy dates can be a challenge. The development of pregnancy is counted from the first day of the woman’s last normal menstrual period (LMP), even though the development of the fetus does not begin until conception, which is about two weeks later.<\/p>\n

Pregnancy is calculated from this day because each time a woman has a period, her body is preparing for pregnancy. Counting from the LMP, most women are pregnant an average of 280 days<\/strong>. Calculating from the LMP also gives a standard of measurement for health care providers to follow since it is extremely difficult to know exactly when conception occurred.<\/p>\n

For more information on how pregnancy is measured, please see our information on calculating your dates.<\/a><\/strong><\/p>\n

What changes are occurring with your body?<\/h3>\n

Your period has just begun, and you may be thinking about becoming pregnant. Your ovulation<\/a> time is the most important thing you need to understand when trying to conceive. Ovulation occurs when a mature egg is released from the ovary, pushed down the fallopian tube, and available to be fertilized.<\/p>\n

The lining of the uterus has thickened to prepare for a fertilized egg. If conception does not occur, the uterine lining will be shed. The shedding of an unfertilized egg and the uterine wall occurs during menstruation<\/a>.<\/p>\n

There are also several facts that you need to know concerning ovulation:<\/strong><\/p>\n
