Water break or discharge??

So I got up this morning and peed like I normally do along with the 5 times I get up already at night. Go sit on the couch when I'm done and my underwear and shorts are wet... I do insert EPO at night but by the time 2/3 am rolls around I've already peed so many times I'm sure there's nothing left up there. My underwear/shorts were not oily like the EPO tabs and it definitely wasn't urine. I was just at L&d last week bc I thought my water was ruptured and it wasn't. Don't want to be a hypochondriac and go right back to hear the same thing. Is there anything I can do to try to figure this out on my own or is going to doctors the only way? I had some serious cramps/contractions but nothing consistent all last night and woke up w cramps but still nothing consistent or extremely painful like everyone says real contractions are. Needing some advice! Thanks!
