If, on speculum exam, you see fluid running from the cervical os, then
there is either ruptured amnion or a vesico-uterine fistula. The rarity of
the latter, especially presenting anew in the third trimester usually is
sufficient to rule it out.

Actually, I have seen an effort at ferning which failed during the
9th month of my G2Ppre1 wife. Unfortunately the amnion had
probably ruptured and self-repaired because the baby was
born with GBS about 96 hours later. Ferning, I think,
is an imperfect assay. No paper was around at that
particular office at that particular time, but the fluid
leak was running clear and not ferning.
Of course, Dr. Ramirez is right that that was my single
experience.
