What should I do if I think I am leaking amniotic fluid?

I am now 37 weeks pregnant and I think I might be leaking amniotic fluid but I'm not sure. Also i woke up this morning and went to the bathroom and after i was done I went in my closet and leaked out a puddle of water, it was clear but I wasn't sure if it was urine or amniotic fluid, and have been having very small leakage.
