Introduction

• Pregnancy is the period during which a baby develops inside the uterus, typically lasting 40 weeks from the first day of the last menstrual period.
• These 40 weeks are grouped into three segments called trimesters.

First Trimester

• The first trimester lasts about 13 weeks.
• During the first two weeks, you aren’t actually pregnant, but your body is preparing for pregnancy.
• During the second week, an egg is released from your ovary in a process called ovulation.
• At the end of the second week, conception or fertilization occurs when a sperm from the father merges with the egg from the mother, usually in the fallopian tubes.
• During conception, genetic material from the mother and father combine to form a unique genetic code, determining sex, hair color, eye color, and other characteristics.
• This new single cell is called a zygote or embryo, the beginning of a new human being.
• During the third week, the zygote divides to form a hollow ball of cells called a blastocyst.
• The cells of the blastocyst begin to arrange themselves into two groups: the inner group will develop into the baby, and the outer group will form tissues to nourish and protect it.
• During week four, the blastocyst moves into the uterus, where it hatches out of its outer layer and embeds itself in the uterus in a process called implantation.

Embryonic Period

• Weeks five to ten are referred to as the embryonic period.
• All of the major organs start to grow, such as the brain, spinal cord, and heart.
• The heart begins to beat during this period.
• Structures called the placenta and umbilical cord begin providing life support for the embryo, bringing nutrients and oxygen from the mother to the embryo.
• Bones and muscles start to grow beneath thin, transparent skin.
• Toward the end of the embryonic period, the embryo starts to look more human.

Fetal Period

• At the end of week 10, the embryo is now called a fetus and is about one and a quarter inches long from head to rump.
• During the next few weeks, the arms and legs grow longer and start to move, fingers and toes finish developing, and the baby’s face becomes well-formed.
• By the end of the first trimester, your baby is almost three inches long.

Physical Changes

• Your body experiences many changes during the first trimester due to changing levels of hormones circulating through your body.
• The most common first sign of pregnancy is that your menstrual periods have stopped.
• Other symptoms may include nausea (often called morning sickness), tender and swollen breasts, mood swings, constipation, weight loss or weight gain, cravings or dislikes for certain foods, and feeling more tired than usual.
• If you have any questions or concerns about how your baby is developing or how you’re feeling, talk to your healthcare provider.

Conclusion

• Pregnancy is a complex and amazing process that involves many changes in your body and the development of your baby.
• Stay informed and consult with your healthcare provider if you have any questions or concerns.
