Ugh not sure water breaking

So I went to bed tonight at 8pm exhausted from not sleeping well the past few nights. It is now midnight and I am wide awake wondering if my water broke. I woke up three times to the feeling of a small release of fluid and a small wet spot in my bed. At first I thought I was just leaking a little urine or having excessive discharge so I got up, peed a little, and went back to sleep. The third time i thought WTF and really woke up, turned the light on and checked it out. It has no odor or color, and took a little while to completely clean up in the bathroom.   I've changed my clothes etc and put a pad on so I can monitor better. I am feeling crampy but no contractions. I guess I didn't expect to be wondering if this is it. If it isn't my water breaking, and just a glamorous side effect of pregnancy, I'd really like to get some sleep.
