Hi,
Welcome to HCM.
She is most likely having white discharge.
If it is odourless, watery in consistency, then there is nothing to worry. In
pregnancy there may be slightly more discharge. This discharge will cause itching. Ask her to regularly clean the area with water, preferably with some antiseptic solution added to water such as Savalon, which is available in all medical shops.
If the discharge is foul smelling , yellowish green in colour or thick white curd like, then you should consult a gynecologist who will have to examine and treat accordingly.
Of course leaking of
amniotic fluid has to be also ruled out.
