leaking?

I know I won't know 100% unless I go to L&D but I hate to go and it be nothing.. the past few days my underwear has felt like I've been sweaty, it's not enough to get through my pants. I have a friend who leaked so little that she didn't know her water broke so I'm pretty concerned.. I wore a pad last night and it wasn't completely soaked, but it did have liquid on it. has anyone else had a similar experience? I have an appointment tomorrow morning and I'll ask then if I don't end up going tonight.. I'm just not sure what exactly to do. I'm 20 and my mom is the one helping me, I don't want to bother her for nothing if I don't have to
