I'm in preterm labor. I have some questions. Please help!

Yesterday when I went to the toilet, this clear watery stuff started coming out (a couple gushes with consistant dripping--along witha few cloudy drips). I know it wasnt pee cause I started and finished peeing (at an angle) while the watery stuff was still dripping straight down. And I could feel it coming from the vigina (vagina) opening. I would say there was about 3 tablespoon fulls. I went to the hospital but after some testing I was sent home. They said that because the ultra sound showed normal amounts of fluids, they could only assume that my water did not break. But I'm not so sure.What else could that have been? I dont think it was just discharge because if it had happened with my pants on it would have been running down my leg. Could there be a leak that they couldn't detect???

I left the hospital at 5 and at 7:45 I started having contractions that were 4/hr for the next 5 hours (then I fell asleep) this morning they had slowed to 1/hr but at 3:20 they started up again to 4/hr.
I am on medication to stop the contractions but Im having more than I was before I was on the meds.

I'm really worried because I'm only 28w2d and 3 days ago I was put on bed rest because I was almost 2cm dilated and very soft. I lost my mucus plug 2 weeks ago.

Does this leaking sound normal and can these contractons be making me dilate more even though they are irregular??
