Pregnancy• Conception occurs when a sperm and egg
join• The fertilized egg is called a zygote• The zygote implants into the uterine lining.• The placenta and umbilical cord begin to form• The endometrium becomes thicker and the
cervix is sealed by a mucus plug

How Pregnancy is Determined
• 1. Absence of menstruation• 2. hCG – Human Chorionic
Gonadotrophin is released into the blood stream (What is detected by pregnancy tests)
• 3. Morning sickness

Development• The developing
baby is called an Embryo until the 2nd month
• After the 2nd month the baby is called a Fetus

Tests done during pregnancy• Amniocentesis – a diagnostic procedure in
which a needle is inserted through the uterus to extract fluid from the amniotic sac.
• Amniotic sac – pouch of fluid that surrounds a fetus
• Ultrasound – another diagnostic procedure used to monitor the fetus• High-frequency sound waves are used to provide
an image of the developing baby

Going into Labor
• The process of childbirth is called Labor
• Signs of Labor• Lightening • Bloody Show• Contractions• Water Breaking• Cervix Dilation
![Page 8: Pregnancy and Childbirth It’s a…. Pregnancy Conception occurs when a sperm and egg join The fertilized egg is called a zygote The zygote implants into.](https://reader036.fdocuments.us/reader036/viewer/2022081520/5697c00c1a28abf838cc8c33/html5/thumbnails/8.jpg)
Going into Labor• Lightening
• When the baby lowers into the lower pelvis area• Can occur weeks, days, or hours prior to labor
• Bloody Show• The mucus plug covering the cervix is expelled• Happens when the cervix begins to dilate• Can be clear, pink or bloody

Going into LaborContraction Characteristics False Labor True Labor
How often do the contractions occur?
Contractions are often irregular and do not get closer together.
Contractions come at regular intervals and last about 30-70 seconds. As time goes on, they get closer together.
Do they change with movement?
Contractions may stop when you walk or rest, or may even stop if you change positions.
Contractions continue despite movement or changing positions.
How strong are they? Contractions are usually weak and do not get much stronger. Or they may be strong at first and then get weaker.
Contractions steadily increase in strength.
Where do you feel the pain? Contractions are usually only felt in the front of the abdomen or pelvic region.
Contractions usually start in the lower back and move to the front of the abdomen.

Going into Labor
• Water Breaking• This is the rupturing of the amniotic sac• This should occur within 24 hours of
delivery• The doctor sometimes has to rupture the
amniotic sac• Can feel like a sudden gush of fluid or a
constant trickle

Going into Labor
• Cervix Dilation• The stretching and opening of the cervix• During pregnancy the cervix will dilate up
to about 10 centimeters• Labor occurs when the cervix is dilated
completely

Stages of Labor
• 1. Dilation of the Cervix• 2. Delivery of the Baby• 3. Delivery of the afterbirth (placenta)
![Page 13: Pregnancy and Childbirth It’s a…. Pregnancy Conception occurs when a sperm and egg join The fertilized egg is called a zygote The zygote implants into.](https://reader036.fdocuments.us/reader036/viewer/2022081520/5697c00c1a28abf838cc8c33/html5/thumbnails/13.jpg)
Dilation of the Cervix
• The first stage of labor can last for hours.
![Page 14: Pregnancy and Childbirth It’s a…. Pregnancy Conception occurs when a sperm and egg join The fertilized egg is called a zygote The zygote implants into.](https://reader036.fdocuments.us/reader036/viewer/2022081520/5697c00c1a28abf838cc8c33/html5/thumbnails/14.jpg)
Birth of the Baby• The 2nd stage the baby moves head first
through the birth canal and out the vaginal opening. This can last for a few hours or more.
• Crowning – The appearance of the baby’s head during delivery
• Once the baby is outside the birth canal and begins to breath on its own, the umbilical cord is cut

Delivery of the Afterbirth
• The 3rd stage – the delivery of the placenta (afterbirth)
![Page 16: Pregnancy and Childbirth It’s a…. Pregnancy Conception occurs when a sperm and egg join The fertilized egg is called a zygote The zygote implants into.](https://reader036.fdocuments.us/reader036/viewer/2022081520/5697c00c1a28abf838cc8c33/html5/thumbnails/16.jpg)

Complications
• Cesarean Section – a procedure in which the baby is removed from the mother by making an incision in the abdomen
• Often needed when a child is breech
