Pre-term labor concern?

Yesterday I had green mucus discharge in the morning low, sharp pains in my abdomen and vagina, then last night I had sharp back pains every couple of minutes. Today I feel fluish, have diarrhea, back pain and in one hour had 5 bh contractions.

I very much hope these are not signs of pre term labor, but I am concerned. I haven't called my dr because I have a 32 week appt today at 3:30.
