is it time?

rhetorical question obviously... But I lost my mucus plug this morning in the shower, had pretty intense contractions 10 min apart all night long and was 2cm dilated yesterday at doc. When I got out of the shower I thought my water broke, had discharge down my leg, then... Nothing. No more leaking, and contractions stopped. I called off work and now feel like I should have gone in. Taking it easy but did run to the grocery store and got a few things.
