Uterus changes
•Hypertrophy
•Braxton-Hicks contractions
•Softening of isthmus of uterus—Hegar's Sign (6-8 weeks).
•Contains 1/6 of maternal blood volume end of pregnancy
Fundal height
•Fundus palpable:
•Symphysis pubis: 10-12 weeks
•Level of umbilicus: 20-22 weeks
•McDonald's Method: Most reliable between 22-34 weeks
Ovaries changes
•Ovum production ceases
•In early pregnancy, human chorionic gonadotropin (hCG) helps to
maintain the corpus luteum for 6-8 weeks
•Progesterone from corpus luteum maintains the endometrium until
placenta takes over progesterone production at 10-12 weeks
Cervix changes
•Estrogen stimulates glandular tissue of the cervix
•Number of cervix cells increases
•Thick mucus forms the mucous plug
•Goodell's sign - softening of cervix
•Chadwick's sign - bluish color (increased vascularization)
Vaginal changes
•Estrogen stimulates hypertrophy, hyperplasia, increased
vascularization (Chadwick's sign) and relaxation of tissues at term
•Thickening of mucosa
•Loosening of supportive connective tissue
•Increase in vaginal secretions (leukorrhea)
, •pH low (acidic) - helps to prevent infections but makes more
susceptible to yeast infections

•Metabolic rate increases by 20-25% to meet fetal metabolic needs
•Total serum thyroxine T4 increases and stays up until after birth
