Leaking amniotic fluid.?

I am 33 weeks along and just realized that I might have been leaking amniotic fluid for some time after doing some research. My underwear gets wet spots or is damp all over throughout the day and the smell is sweet. I have been lucky this pregnancy to not have a lot of discharged so sometimes that's all I have is damp underwear. I also just got positive test results back for a yeast infection so am wondering if dampness is a symptom. Is there anyway I could do an at home test to check if am really leaking or has anyone had the same experience and what we pas the outcome.
