Woke at 4:30 am with wet legs and a yellowish watery substance down my legs. Why?:confused:

You SHOULD see a doctor. I don't want to scare you. I receive my weekly updates about my pregnancy from babycenter.com and it said when your discharge changes to watery yellow and a few other examples, that seeing a doctor was a MUST. It could be a sign of early labor. I DON'T WANT TO WORRY YOU...EVERY WOMAN IS DIFFERENT, BUT PLEASE SEE A DOCTOR.

It sound like you have a leak in your bag of water. Call your doc or call the hospital and see what they say, I have had a problem when my water was leaking also, it wasn't a major problem just casused for s dry birth. Nother the less CALL THE DOC ASAPPPPP

PLEASE
And then let us know that everything OK please...

Agree with the others... could be simply a urine leak, could be a leak in the amniotic sac, could be neither and just watery discharge. Increased discharge is fairly normal towards the end of pregnancy. When in doubt, have it checked.
