Waters or normal?

Can your waters go without you knowing? Or start to go? I’m 37 weeks 1 day, was out with my partner and said I felt really wet, came home went to the toilet and my underwear are literally soaked! My partner said there is a smell but not pee or a discharge smell. I’ve put a pad on instead of going up to the hospital. I’ll post a photo in the comments so you can see how wet I mean. So sorry for that. Also a photo posted after leaving a pad on.
