I had no signs

Nope

Not exactly but I believe each woman has bloody show at one point in time either right before or during active labor.

With my oldest I had my bloody show about 2hrs into labor.

I'm unsure about when I had it with my youngest.

Yes ma'am, The bloody show is a sign that labor is impending. Losing your mucus plug, which is often accompanied or followed by the bloody show, usually happens right before labor starts or several days before. ... Some women don't have a bloody show until they're actually laboring.
