Thanks for writing your query.
I would advise you to get an ultrasonography
on urgent basis or meet your doctor who can do a sonography for you. It is very difficult to predict anything like this. But you should get sonography that will help us to know the condition of the fetus. Normally the vaginal discharge
increases during 5th month of pregnancy
but if it is more watery than you should consult your doctor soon.
Dont worry & take care.
