Water didn't break at 34 weeks

I posted yesterday that I thought I had sprung a leak.  I decided to go get checked to make sure, and they did some tests.  One came back positive (the paper test) but it wasn't a strong positive, so they did a smear on a slide to look under the microscope.  That test came back negative.  So, they aren't sure why I got a + for the first test, but they didn't think I really have a leak.  While I was there I was found to have an "irritable uterus" though, but they couldn't give me terbutaline because my heart rate was already high (I was pretty nervous).  After a couple hours and drinking some water, they let me go home.  I really don't have any restrictions or anything - just supposed to take it easy the rest of the weekend.  I am oked to go to work Monday.  I am just really glad everything turned out ok, though I am a little embarrassed that my water didn't break and it was probably urine running down my leg.    Ah, the joys of pregnancy!
