What Causes Clear Liquid Discharge From The Wound Post Cleansing A Gashed Shin?

I gashed my shin open while I was way out in the woods. I rinsed it with saline solution, picked up the wrong cleansing pad that had alcohol and lite myself up. I pulled the meat and skin from under the upper part of my leg. Cleanse it the proper way, dried with a gauge sponge after pulling the skin back down. I closed it up as much as one person could and put on steri-stripes. I covered the strips with liquid skin, wrapped the wound and made the trek back to my tent. Things have gone well, except after 10 days, it started leaking a clear fluid when I was standing. What is this clear liquid? This wound does not look infected and I have been taking an antibiotic. I had the clear liquid leak out of another would a long time ago and it was infected. But you could tell it was infected.
