Answer: As the baby moves down, your cervix will thin out creating some watery discharge. Totally normal :). However please try to analyse the sort of discharge -
1) If you're leaking urine, the fluid will likely have a distinctive odor.
2) If you're leaking vaginal fluid, the discharge will probably be clear or white to yellowish. It can be rather sloppy, requiring multiple changes of underwear or panty liners in a single day.
3) If you're leaking amniotic fluid or your water has broken, the fluid is likely to saturate your underwear or panty liner over and over again. The fluid may be clear or contain white flecks, perhaps tinged with blood or mucus. It isn't likely to smell, however. If your are leaking amniotic fluid it won't stop and you'll get a big gush when you stand. In case you are soaking through a pad in an hour please call the doctor.
