Pregnancy: The First Trimester

If you are trying to get pregnant, then you need to make sure that you are healthy, in shape and are eating healthy foods. It's also best to begin taken vitamins to improve your immune system and make sure that your baby will be in perfect health. You will want to check for any STD's and get them treated as well.

The first trimester consists of the first thirteen weeks of your pregnancy. This will hopefully give you a idea what will be happening to you and your baby from week.

In week one of your pregnancy you will have you period just like any normal month. In most cases you will not have another period until after the baby is born. There are some cases, however, in which the mother has her period through-out her entire pregnancy, but this is rare. If you do experience bleeding throughout your pregnancy call your doctor immediately.

Your due date is determined by the first day of your last period. Simply subtract seven days from the first day of your period and then add nine months. Since most women don't know when the date of their baby's conception was, this is another way to get a rough idea of when your baby will be due.

In the beginning of the second week, your period has ended and within your uterus there is forming a new endometrium layer in preparation for the baby. Though you are not ovulating yet your body is in the process of "ripening" egg. When you begin to ovulate you estrogen levels will rise and you may feel a lot of energy at this time that you do not other wise feel.

Ovulation takes place in the third week. During ovulation, your body releases more pheromones than usual and you become more attractive to the opposite sex. The ovum (egg) is on its way to the uterus. Though the male may produce any where between 140 and 350 million sperm during intercourse, only about 200 will find it's way to the ovum. Eventually, somewhere between 12 and 24 hours after you ovulate, a sperm makes contact with the egg and still has mobility enough to enter the outer layers of the egg. Thus, begins a new life.
