I'm 32 weeks and I have been getting it too and the doctor checked me on Monday and she said I was still closed and she didn't think it was amniotic fluid but they are testing it to see and they also took a few more samples just to be safe of what it could possibly be. But if you haven't seen your doctor yet, I would give them call to be safe :)
Put on an unscented pad. After you notice some leakage, smell it. If it's sweet smelling it's amniotic fluid, if it' not then it's urine.
If I were you I would call your Dr or go to l&d. They can test the fluid to make sure its not amniotic fluid.
Place a pad on so you can check colour and smell. If your soaking a pad then you may have a slow leak and will need to see a doctor.
