Don't worry, they are on their own schedule and never ours. I have had some go more than a week between sweating and pipping before. You will have pippers in no time and then I hope you have your fruit flies ready to go! Congrats on the progress.
The "sweat" is amniotic fluid, not just water, so I wouldn't worry one bit about the color. Give it a month, and then tell me again that you have tons of fruit flies. LOL I probably go through 24 large cultures a month when raising babies.
