Hi Sara
With my previous pregnancy I was the same, I was about 36 weeks, and noticing so much watery discharge, I couldnt sometimes be sure if it was just that, or if I was having trouble controlling my bladder. I sometimes felt that there was so much, I must have wet myself a bit. i went to the hospital and had an exam, and it turned out, I did have a small leaf in my waters, and at 38 weeks, had to be induced to avoid infection. Maybe you should just keep an eye on it, and if it starts getting to be ridiculous amounts, get a second opinion from another dr. All the best!
