Question Title: Pregnancy and cervical positioning and mucus???? Need questions answered...

Dear Gypsy:
Cervical mucus during the days of menstrual flow is invisible amidst the blood. Following menstrual flow, the mucus is small in amount, thick, non-stretchable. Under the influence of estrogen, the mucus increases its content of salt and water: thus, it becomes thin, runny, stretchable and remains so until ovulation. Following the egg release, progesterone causes the mucus to have less salt and water: thus it is thick, tacky, poorly stretchable. It remains so until the next menstrual flow and the cycle repeats.
Pregnancy is a progesterone-dominated time: the mucus is thick, tacky, poorly stretchable.
Concurrent with cervical mucus, the vaginal walls secrete moisture. This secretion is often white, milky, variable in consistency.

The cervix changes position as the uterus changes its size and position. In 75% of women, the uterus tips forward and the cervix tips backwards; in 25% of women, the reverse is true. The fullness of bladder and large bowel influence the position of the uterus and hence the cervix. During early pregnancy, as the uterus grows, it becomes heavier and intially falls either more forward or more backwards, depending on original position. This causes the cervix to exaggerate its location against the back for front wall of the vagina, respectively.
