2. 10. Abdominal bloating 9. Heightened sensitivity to odors 8. Nausea or vomiting 7. Frequent urination 6. Fatigue 5. Tender, swollen breasts 4. A missed period 3. Implantation bleeding 2. Your basal body temperature stays high 1. The proof: A positive home pregnancy test

3. CAUSED FROM CHANGES IN HORMONE LEVELS

4. Can be heard with a stethoscope At 20-24 weeks

7. FIRST SIGN OF LABOR Water breaking, loss of mucus plug

8. The first stage begins with the onset of contractions that cause progressive changes in your cervix and ends when your cervix is fully dilated. This stage is divided into two phases: early (or latent) and active labor. During early labor, your cervix gradually effaces (thins out) and dilates (opens). During active labor, your cervix begins to dilate more rapidly and contractions are longer, stronger, and closer together. People often refer to the last part of active labor as "transition." The second stage of labor begins once you're fully dilated and ends with the birth of your baby. This is sometimes referred to as the "pushing" stage. The third and final stage begins right after the birth of your baby and ends with the separation and subsequent delivery of the placenta.

9. THE BABY IS BORN IN YOUR 2 ND STAGE OF LABOR

10. A BABY BEGINS TO BREATH ON ITS OWN A SECOND AFTER BIRTH

12. *The placenta is responsible for working as a trading post between the mother's and the baby's blood supply. * Small blood vessels carrying the fetal blood run through the placenta, which is full of maternal blood. * Nutrients and oxygen from the mother's blood are transferred to the fetal blood, while waste products are transferred from the fetal blood to the maternal blood, without the two blood supplies mixing.

13. A premature baby, or preemie, is born before the 37th week of pregnancy. Premature birth occurs in between 8 percent to 10 percent of all pregnancies in the United States. Because they are born too early, preemies weigh much less than full-term babies. They may have health problems because their organs did not have enough time to develop. Preemies need special medical care in a neonatal intensive care unit, or NICU. They stay there until their organ systems can work on their own.

16. FUNCTION OF THE UMBILICAL CORD:

17. *The main function of the umbilical cord is to carry nourishment and oxygen from the placenta to the baby and return waste products to the placenta from the fetus. *Oxygen, nutrients and antibodies from you diffuse into your baby’s blood and waste materials from the baby pass into your blood by 2 un-oxygenated arteries *Approximately 22 inches long *No nerves so is not painful when cut *Cord contains 2 arteries that carry deoxygenated blood from the fetus back to you, and one vein that carries oxygenated blood from you to the fetus

18. CrowningCrowning: When the baby's head has passed through the birth canal and the top or "crown" stays visible at the vaginal opening.

19. AMNIOTIC FLUID Supports the fetus during pregnancy Produced as early as 2 weeks after conception Helps baby to move around in womb Supports the development of the baby At first mostly water, then contains electrolytes, proteins, fats and carbs. By 20 weeks, mostly fetal urine Protect baby from physical shocks from outside By allowing baby to move around, it helps baby to develop muscles
