TMI pee or amniotic fluid?

I'm almost 39 weeks. I have incontinence issues from giving birth last time when they need up my Cath, so I stays wear pantyliners. Today I noticed it feeling wet all the time, but it wasn't yellow like pee, most of the time anyways. I just changing it. I also noticed that when I do go pee it smells sweet almost. I haven't had any gushes or anything, but could I be leaking fluid? I did not drink more than any other typical day that my pee would constantly be clear. I leaked last pregnancy and it wasn't ever caught until the doctor went to break it and there wasn't any to break. I see my doctor late morning tomorrow and will ask but I'm freaking out a bit because of it and also because I'm unsure I'll make it to doc for certain because we are in a blizzard warning and I'm 30 min from hospital on a regular day.
