Just out of curiosity what are the symptoms??

Last couple of days I have been having a trickle of clear discharge with ammonia smell to it? And has been on my mind that maybe my waters are broken (I am 24weeks)I am only thinking this cause during intercourse (sorry TMI) both me and DH felt something weird? And I thought maybe that was the sac? And we perhaps pushed things too far (would I have definitely known??)

Sorry if silly question - first pregnancy
