preterm labor.

I'm 32 + 2 and was in the hospital on Friday night for preterm labor contractions. They gave me some capsules and a shot to stop them. Now today when I peed earlier I noticed a TON of whitish yellow slimy discharge. The discharge stopped for a while but I had off and on menstrual like cramping with nausea and abdominal tightness, and just a few minutes ago I got a little bit more slimy discharge. I feel better laying down and am chalking it up to me being extremely stressed lately. I'm terrified of my baby coming early. My OB's nurse talked to me like I'm stupid and said she'd get back in touch but I just want some real advice. I've been on high alert since I've gotten home from the hospital and put on temporary bed rest :(
