Dear madam,I understand your concern.there are different causes of discharge during pregnancy like vaginal infection ,leaking amniotic fluid,cervical show at time of labour pains.In the vaginal infection discharge differs depending on the cause like curdy white and itchy in candidiasis( most common in pregnancy),yellowish mucoid discharge and foul smelling in bacterial vaginosis. in case of leaking fluid that will be clear and white and you see like a gush coming out.at the time of labour pains you see a reddish brown mucoid discharge.but dont worry , just check for the baby movements but definitely see your ObGy to know the cause and further management.
