Quick Facts About Pregnancy


Do you want to get pregnant? Or do you want to avoid getting pregnant?

Either way, it’s important to learn as much as you can about how your body works. This is also good information to share with your daughters.

Ready to learn? Take a few minutes to read through these quick facts about pregnancy.

Remember, these are just guidelines based on what most girls and women experience. Every body is different, so be sure to ask your doctor if you have questions.

First, your body must release an egg. Eggs are located in a woman’s ovaries. There is one ovary on each side of the uterus.

After the egg leaves the ovary, it moves to the fallopian tube. This is called “ovulation.”

The next step is a sperm cell connecting with the egg, most often in the fallopian tube. This is called “fertilization.”

Sperm usually enter the woman’s body during intercourse. They can enter the woman’s body during other types of sexual activity as well.

Yes, girls can get pregnant before they get their first period.

A monthly period is also called a “menstrual cycle.” Many girls get their first period around age 12. Other girls start their menstrual cycles before or after age 12.

Most of the time, if an egg is released from the ovary, and it does not get fertilized, a menstrual cycle will follow several days later. During this menstrual cycle or period, the bloody lining of the uterus moves down and out of the body.

If a sperm and egg meet at just the right time before a girl’s first menstrual cycle, she can become pregnant.

When the fertilized egg moves out of the fallopian tube, it enters the uterus. If it attaches to the wall of the uterus, that is known as implantation.

The fertilized egg grows in the uterus. First it develops into an embryo and then into a fetus. Most pregnancies last from 38 to 42 weeks.

Each female body is different, so these numbers are just averages.

Every 28 days or so, the ovary releases one egg. When the egg moves into the fallopian tube, it stays in the tube for about 24 hours.

If sperm does not fertilize the egg during these 24 hours, the egg will disintegrate.  

About 11-16 days later, the lining of the uterus will move out of the body, and the girl or woman will experience this as “getting her period.”

Ovulation is different for everyone and it can change from cycle to cycle — especially when you are a teenager and your body is still developing.

You can estimate your ovulation date by using a fertility tracker.

An egg stays in the fallopian tube, available to be fertilized, for about 24 hours.

However, sperm can live inside the body for up to five days.

You can have sex before you ovulate and still become pregnant. For example, sperm that entered your body on Saturday could fertilize an egg released on Wednesday.

Most eggs are fertilized by sperm while still in the fallopian tube. The fertilized egg then travels down the fallopian tube into the uterus. This can take 1-2 days.

Many fertilized eggs do not implant in the uterus wall. Instead, these eggs leave the body with the next period.

No, but there are certain times when pregnancy is less likely to happen.

If you do not want to become pregnant, use birth control, also called “contraception.” There are many kinds of birth control. Ask your doctor which one is best for you.
