  1. Fetal Development How babies come to be…

  2. An egg goes down the fallopian tube after ovulation; if a sperm makes its way from the vagina through the uterus to the egg within 24 hours, conception is likely to occur.

  3. A sperm penetrates the egg and conception occurs. It is called a zygote until it reaches the uterus in 3-4 days. Egg surrounded by sperm.

  4. This means… You’re Pregnant!!Even though you probably have no idea

  5. Signs and Symptoms of Pregnancy • A missing menstrual period • Morning sickness and nausea • Frequent urination • Cravings • Breasts enlarge • Fatigue and dizziness A simple urine test from the doctor will show whether or not a woman is pregnant.

  6. The embryo may float freely in the uterus for about 48 hours before implanting. Upon implantation, complex connections between the mother and embryo develop to form the placenta.

  7. Other considerations: • No medications, including over-the counter drugs, unless approved by your doctor. • No drugs or alcohol. • No x-rays. • No saunas and hot tubs. • No vaccinations during pregnancy. • Avoid cats, cattle, sheep and pigs. They have a parasite that causes toxoplasmosis.

  8. First Month 1 Month By the end of the first month, the embryo is about 1/4 of an inch long. The heart, no larger than a poppy seed, has begun beating. Head, mouth, liver, and intestines begin to take shape.

  9. Two Months The embryo grows to about an inch long and has distinct, slightly webbed fingers. Veins are clearly visible. The placenta is already nourishing the baby through the umbilical cord. The heart has divided into right and left chambers. Veins are clearly visible. Most vital organs are developed.

  10. Three Months Starting at eight weeks, your baby is called a fetus. By the end of the first trimester, the fetus is 2 1/2 to 3 inches long and is fully formed. It has begun swallowing and kicking. All organs and muscles have formed and are beginning to function. The arms, legs, hand, and fingers are fully developed. The nails on its fingers and toes are starting to develop.

  11. What’s going on with Mom? • Skin – Every woman’s body reacts differently to pregnancy. • Oily, dry or scaly • Stretch marks • Facial skin may darken • Emotions • Need a few extra breaks or time to relax. • May experience mood swings, depression and bad dreams. • Feel baby’s movements

  12. Four Months Your baby is about 8 inches long and is covered with a layer of thick, downy hair called lanugo. The first outlines of the face are showing. His heartbeat can be heard clearly. This is when many mothers feel their baby's first kick.

  13. Five Months If you have an ultrasound, you might see him sucking his thumb. By the end of this month, your baby will be nearly 12 inches long and weigh almost a pound. The skull bones are the most important bones being developed at this time. At this point (20 weeks) an ultrasound will show the sex of the baby

  14. Six Months Tiny eyebrows and eyelids are visible. There is a lot of evidence to show that the baby can hear the outside world. Your baby's lungs are filled with amniotic fluid, and he has started to practice breathing movements. If you talk or sing, he can hear you. Fingerprints are formed.

  15. What’s going on with Mom? • Abdomen enlarges • Fatigue is common • Expectant fathers take more interest because they can feel the baby move. • Baby moves a lot • A mother should feel the baby move every couple of hours. If not, she should call her doctor.

  16. Discomforts that might be experienced • Heartburn • Shortness of breath • Heart palpitations • Leg cramps • Round ligament pains

  17. By the end of the seventh month, your baby weighs about 2 ½ to 3 pounds and is about 15 inches long. His body is well formed. Fingernails cover his fingertips. He may try to turn toward a source of bright light. Seven Months

  18. Eight Months Your baby is gaining about half a pound per week, and layers of fat are piling on under his skin. He has probably turned head-down in preparation for his coming birth. He weighs between 4 and 6 pounds.

  19. Nine Months Your baby is a hefty 6 to 9 pounds and measures somewhere between 19 and 22 inches. The lungs develop in preparation for breathing and the head is now head-down. As he becomes more crowded, you may feel him move around less. The last few weeks, the baby “drops” in preparation for delivery – giving the mother a little breathing space.

  20. Baby’s Arrival

  21. Baby – 7 ½ pounds • Placenta – 1 ½ pounds • Uterus – 2 pounds • Amniotic fluid – 1 ½ pound • Extra blood and water – 4 ½ pounds • Breast tissue – 3 pounds • Maternal stores of protein – 4 pounds Weight gain during pregnancy 25-30 pounds

  22. Vaginal bleeding • Sharp abdominal pain or cramping • Loss of fluid from the vagina • Severe or prolonged nausea or vomiting • Frequent dizzy spells • Painful urination • High fever over 100 degrees F. • Vaginal discharge that is irritating Warning Signs Something May Not Be Right Call the doctor if any of the following occur:

  23. Complications • Miscarriage • Toxemia • Ectopic Pregnancy • Stillborn • RH Factor

  24. Mother unable to get rid of babies waste (liquid waste) • High Blood Pressure, swelling, protein in blood, headache • Treatment- Bed rest, early C-section • If not treated may cause convulsions and/or death of mother and baby. Preeclampsia (Toxemia)

  25. High sugar level … woman unable to detect. • Test can detect excess sugar in urine; high blood pressure • Treatment- diet Gestational Diabetes

  26. Blood types do not match (mother RH neg. and baby RH positive) • Treatment- Vaccination to destroy the antibodies that harm baby (28th week of pregnancy and 72 hours after delivery) • Death of infant RH Factor

  27. Placenta detaches from uterus wall. • Blood in water/ urine • Treatment- C- Section • Stillborn death Abruptio Placenta

  28. Placenta covers the cervix or close to it. • Bleeding in last trimester • Treatment- Bed rest, C-Section, Blood transfusion • Early labor, death of baby Placenta Previa

  29. Miscarriage- before 20 weeks • Stillborn- after 20 weeks
