is it my waters

anonymous

when i was near my due date with my 3rd baby.... i had a strong vinegar smell down below...... very very strong and when i went down about it turns out it was amniotic fluid leaking and they started me. now with my 4th i am 3 weeks before my due date but suddenly feel dampish with a light pinkish stain to my pants and a foul smell could it be my waters again?
