indication of labor

Haydn
Hey Mommas, what was your biggest indication you were going to go into labor soon? I've been having having to go #2 like crazy lately and have been having massive heart burn. I've had contractions on and off for two months and they've been monitored.  I'm at high risk for early labor around 36/37 weeks, they didn't even think I would make it this far and I'm 35 + 5 today. At my last appt on Monday baby was staged at a -1. He dropped from a -3 to a -1 in one week. Just looking to get some input.
