Basics Of Pregnancy

Before getting into the pregnancy symptoms, you need to know some basic things. A woman’s pregnancy is divided into three trimesters. Each trimester has a duration of more than 13 weeks. The first month you get pregnant marks the start of your trimester. Your doctor uses a certain term during your diagnosis. You can get confused listening to it. So, here is the explanation of the basic terms used to define your pregnancy.

Basics Of Pregnancy

Your pregnancy timing is measured by the doctor/gynecologist using gestational age. It is calculated on the day of your last menstrual period (LMP). So, LMP is the date when you first started your last periods. Many women confuse the gestational age. Most calculate the day they think the conception occurs (mostly on the 14th day from the first day of periods). But, pregnancy is measured three to four weeks before you get pregnant (starting from the first day of your last periods). So, a full term pregnancy is calculated as 40 weeks from your LMP. If your periods are not regular or you do not remember the date, then your doctor uses an ultrasound scan to find the gestational age.

Pregnancy Symptoms During Week 1-2

Actually, you are not pregnant during the time period. It is the first two weeks when you have your period. After two weeks, your ovary releases a mature egg during the process known as ovulation. Ovulation can happen earlier or later depending on the length of your menstrual cycle. People who have 28 days of the menstrual cycle can expect ovulation on the 14th day.

The egg travels from the Fallopian tubes. The sperm from your partner meets up with the mature egg and combines. The process is referred to as fertilization. If you are trying to get pregnant, then you need to have unprotected vaginal sex. The ideal time is six days leading to the day of ovulation (including ovulation day). You may not suffer from any pregnancy symptoms when the egg fertilizes.

The fertilized egg travels through the Fallopian tube and attaches itself to the walls of your uterus. Before it reaches the womb, it divides into more cells. Once the cells reach the womb, it forms into a ball. The ball of cells floats around the uterus for two to three days. These balls of cells attach to the uterus lining. The process is known as implantation, which takes place six days after the fertilization. The implantation process takes around three to four days to complete. So, you become pregnant once the implantation is complete. In more than 50% of cases, the fertilized egg does not implant in the uterus. So, the egg passes out of the body during your period. It happens due to the incompletion of implantation.
