I only had a show with 2 of my kids [#2 & #3].

#2 I had a mucusy show lat in the arvo, and went into labour 2am the next morning.
#3 I had a show at 9pm at night, he was born the next night.. I didn't think I was in labour with him cause it didn't 'hurt' lol
DH was so happy when I had a show with #3, he'd just arrived at work and got to come home lol

Both were mucusy blood streaked. I didn't 'lose blood' so to speak.
AFAIK labour usually starts within 24hrs

Beautiful birthing to you!!!
