contractions and labor.

I've been having contractions now 2-4 minutes apart since Wednesday. On Wednesday at the doctor I was 0 dilation. But today's Saturday and they are more painful. I just don't know if I should go into L&D. This is my first pregnancy and I'm so confused. I'm also so confused if I've been leaking amniotic fluid. I peed earlier and after dripped in the toilet and it looked cloudy just the drop. What do you'll think?! I don't want to go in and look dumb. Or be the girl who cried wolf.
