Leaking amniotic fluid or discharge

These past few weeks I’ve noticed what I believe is fluid, it’s a very thin and watery consistency but it’s staining my underwear brown and leaving me pretty damp throughout the day, it also has a pretty strong smell(it’s not a bad smell just like a strong vaginal smell). I don’t see it when I wipe only that it’s there when I use the restroom. It’s getting pretty aggravating to have to change several times a day and I can’t stand panty liners. I waiting for a nurse to call me back to ask them for sure but wondered if anyone experienced this? I’m 17weeks
