Advise

Hi I'm just looking for advise. For the past month or so I've had to wear a panty liner just because I find I have discharge a lot, now for the past few days every time I go to the bathroom i have been wet above the liner.. Can anyone tell me if this is my waters gradually coming away or if it's something else. My husband keeps telling me I'm just peeing myself haha but I know for a fact I'm not.. So yeah just want to see what yous think. Sorry for tmi so yous can get an idea what I'm talking about. I'll be 38 weeks on Monday!
