Vaginal or Vulvar Discharge, Pregnant Mare
Summary
True vaginal discharge that originates in the uterus is either a sign of impending foaling or a problem with the pregnancy (infection) and impending abortion.
Occasionally, conditions affecting the vulva or vagina result in a discharge that is not originating from the uterus and does not indicate a threat to the pregnancy. For example, urine containing whitish green crystals that accumulate on the vulvar lips can be confused with vaginal discharge.

What To Do
Assess your mare's general health using the Whole Horse Exam (WHE), paying particular attention to her general attitude and appetite, heart rate and rectal temperature.Evaluate the color and quantity of the vaginal discharge, and try to confirm that what you are seeing is not urine.
Assess the size of your mare's udder, and determine whether there is milk by stripping (milking) a little of whatever secretion is present in the teats into your hand. Note the color of that secretion. Note the mare's breeding dates. Share your findings and concerns with your vet.

your vet's role
When problems with pregnancy are caught early and properly diagnosed, there is a chance that a pregnancy can be spared.
On examination, your vet will evaluate the health of the fetus and placenta using rectal palpation and ultrasound. Your vet uses a vaginal exam to assess the source of the discharge, because it may originate somewhere other than the uterus.
