Third trimester question? slightly tmi*

I know it is normal to have some extra discharge, however the past few days and today especially I have had a lot of clear liquid/watery type discharge. Today it dampened through my panties and leggings. It doesn't have a bad odor, itch or anything and I have had minor minor cramps with diarrhea. I am 27wks+2. Should I be worried it might be amniotic fluid or does it sound normal? I am a ftm, tend to downplay stuff and know nothing but don't want to ignore a problem! Little man had been moving around like normal so he seems ok in there
