Possible Signs of Labor? Possible TMI Warning.

You guys always have the best insight. I am a FTM and I think I have some signs of labor, but I really do not want to get my hopes up.

Possible TMI Warning....

We had an interesting weekend. Saturday I went for a long walk, a swim, and gave in to sex even though it is not very comfortable. About an hour later some clear liquid was running down my leg. Which was gross. There was not a ton and it was not a gush. I never felt a "pop" and there was only that little bit. I was super uncomfortable for the rest of the day. I had some light cramping in my stomach and even my back. It slowed down Saturday night and then I have more on Sunday. I am also convinced I lost some of my mucus plug on Sunday. It was gross. I had some on and off cramping and stayed home from work Monday. Monday I was EXHAUSTED. That night I got into the shower around 9PM. I started having mild cramping that came and went. It was not bad enough to keep me from sleeping. I woke up a few times during the night to tinkle. Every time I would go for a tinkle, I would have a cramp. I called my doctor, and they seem to not be concerned unless I swell, get contractions about 5 minutes apart, or if baby stops moving.

Does anyone have any idea what is going on with me?!?!?! I am really hoping these are early signs of labor, but I have NO idea.
