Thrush is a yeast infection in which you'll have a thick white, cottage cheese-like discharge from your vagina. You'll also typically experience dryness and intense itching near your vagina, vulva, perineum and possibly your anus. Another possible symptom of thrush is pain when passing urine.
This yeast infection can happen at any time during your pregnancy.
Thrush is caused by forms of a fungus called Candida albicans, which can always be found in our bowel. If the yeast grows uncontrolled by other bacteria, then infection happens. Women typically experience yeast infections after taking a course of antibiotics that kills off the good bacteria along with the bad.
Thrush is more common during pregnancy because of the increased vaginal blood flow, which causes a leakage of sugar into body fluids. Excessive sugar aggravates the condition.
