At about 5pm today, my mucus plug came out.
"Mucus plug" = a gelatin-like seal for the cervix which protects the amniotic sac from infection.
This is an awesome sign; it means that the cervix is thining out and dilating in preparation for delivery. For some, labour begins within a few hours, others a couple of days.
I don't know if it was the sweep that did it or the supported squats that I've been doing that helped.
I hope I get awaken by labour contractions tonight/tom morning.
