Diagnosis of Early Pregnancy
2. Morning sickness
1) Fatigue, nausea and vomiting (the 6th week↑ → the 12th week↓ ).
2) Hyperemesis gravidarum protracted vomiting necessitating hospitalization.
3) Causes: HCG, delayed gastric emptying(P↑ )
Diagnosis of Early Pregnancy
3. Urinary symptoms
1) Bladder irritability, frequency and nocturia
2) Causes: increased circulation in pelvis (E and P↑), enlargement of the uterus.
3) Note: urinary infection must be ruled out
Diagnosis of Early Pregnancy
4. Mastodynia
1) the development of mammary ducts (E↑) and alveolar system (P↑)
2) circulation↑→ engorgement of the breasts
5. Constipation
smooth muscle relaxant (P↑)
6. Weight gain
Diagnosis of Early Pregnancy
• Signs1. The changes of genital organs1) Vagina: bluish or purple discoloration (congested
pelvic vasculature). Increased vaginal discharge (E and P↑)
2) Cevix: softening and bluish discoloration. The cervical mucus→ a granular pattern
3) Uterocervical junctionHegar’s sign: a widened zone of softness coupled with
compressibility, resulting in a doughnut-shaped, slightly spongy configuration.
Hegar’s sign
Diagnosis of Early Pregnancy
4) Abdominal enlargement Enlargement of uterus (noticed at the 12th
week)2. Breast changes1) Enlargement and vascular engorgement (6th –
8th week)2) Montgomery’s tubercles (6th –8th week, E and
P↑3) Colostrum secretion (16th week) or secondary
breasts
Diagnosis of Early Pregnancy
• Laboratory tests
1. Pregnancy test
1) Urine HCG test (one step): + or –
2) β-HCG: >25mIU/L
2. Ultrasonography
1) Enlargement of uterus
2) Gestational sac
3) Embryo or fetal pulse
Diagnosis of Early Pregnancy
3. Other tests
1) Progesterone test
2) Cervical mucus examination
3) Basal body temperature (BBT)
Diagnosis of mid or late pregnancy
• Symptoms and signs
1. EDC: +9 or –3 (month), +7 (day)
2. Enlargement of uterus
1) 12th week: 2 finger above the symphysis
2) 16th week: midway between the symphysis and the umbilicus.
3) 20th – 22nd week: at the umbilicus
4) …….
Diagnosis of mid or late pregnancy
3. Fetal movement (FM)
1) The first perception: in the 18th – 20th weeks
2) Diagnosis of pregnancy, duration of pregnancy, the safety of fetus
3) Count: 3 times per day, 1 hour per time. sum×4= FM/12 hours. Normal:≥ 30/12 hours
Diagnosis of mid or late pregnancy
4. Fetal heart tones
1) Heared: the 18th – 20th weeks
2) Normal rate: 120-160bpm
3) Differentiation: umbilical souffle
5. Fetal body
Palpated: outlines of the fetus (the 20th week).
Diagnosis of mid or late pregnancy
• Laboratory tests1. Ultrasonography1) The number of fetus2) Fetal lie3) Fetal presentation4) Fetal position5) Fetal dead or not 6) Placenta and cord (velocity of flow)7) Size of fetus
Diagnosis of mid or late pregnancy
2. Fetal electrocardiography, FECG
12th week
