Uterous

The uterus has three major functions: to prepare a bed for a fertilized ovum, to nourish the developing embryo during pregnancy, and to expel the fetus. Shaped like an upside-down pear, and tilted forwards, it lies within the pelvis and is held in place, along with its two extensions, the Fallopian tubes, by ligaments and folds of the peritoneum. The cervix forms the lower third, connected by a narrow isthmus to the main muscular body of the uterus. The non-pregnant uterus weighs 45–60 g and is 7–8 cm long but its weight increases more than ten-fold by the end of pregnancy.

Cervical discharge

It will be discharge from your vagina. It should be clear and have no smell. It's quite common, and due to the hormonal changes as your body prepares to carry the baby. The mucus at your cervix thickens to become a protective barrier. This is the mucus plug that may or may not come at toward the end of pregnancy. All the activity down there creates the extra fluid that you see as discharge. If there is an odd color or odor, see a doctor immediately.
