Under the influence of pregnancy hormones, vaginal mucosa cells are renewed rapidly and the dead cells are removed from the body in the form of a thick white substance. The discharge can be profuse or in small amounts. So long as it’s not accompanied by burning, itching or an unpleasant smell, and it doesn’t contain blood clots, the discharge is normal. However, it is necessary to consult a doctor to exclude leaking amniotic fluid, threat of termination or fungal and other infections.
