During the second week of pregnancy your uterine lining that helps nourish the baby will start developing and your body will also start secreting follicle-stimulating hormone (FSH). At the end of this week you will have almost completed your menstrual cycle and ovulation takes place (ovary releases an egg into the fallopian tube). This is when conception takes place. So you actually conceive the baby only at the end of the second week.
Out of the 46 chromosomes that comprise the baby’s genetic material only two- one from the sperm and another from the egg helps in determining the baby’s sex. These are called the sex chromosomes. If the sperm that fertilizes the egg has an X chromosome then the baby will be a girl and if it is a Y chromosome it will be a baby boy.
You don’t start feeling any changes in the body during the second week of pregnancy. After 14 days before the beginning of the next menstrual period the body ovulates. The ovary releases the ripened egg and the egg moves down the fallopian tube to meet with the sperm. Millions of sperm travel through the vagina, hundreds of them get into the fallopian tube but only one sperm succeeds in penetrating the egg when fertilization takes place.
You have to bear in mind that this stage will be followed by several regular check ups with the health care professionals often leading to a close relationship with the doctor whom you are consulting. Also you should be conscious to consume lot of protein rich foods and healthy foods rich in iron and calcium to be able to carry your baby to full term.
Though your baby will start developing only from the beginning of the third week, and you may not experience any bodily changes as yet, you must be careful in your pregnancy diet and maintain your ideal weight in the second week to prevent complications later on.
