Leaking amniotic fluid 25 weeks?

Friday morning when I woke up my panties were completely soaked in something and it didnt smell. I put on a pantyliner and went about my day. I noticed later that the liner was totally soaked again, so I changed it out for another one. I've also been having intense back pain today like no other and a dull stabbing pain in my abdomen. When I lie down i also feel like I'm going to pee all over myself even though i just went. (I don't have a UTI.) I'm only 25+2 weeks, could this be amniotic fluid leaking? I'm a ftm and it's freaking me out. I don't know what to do. My husband is at work until 5 with our only vehicle so I cant go to the doctor. If I did it would have to be when he gets here. What does this sound like to you guys?
