38 + 2

HN
(6/9)Had my 38 week appointment today. Cervix is dilated 3 cm and we are 50% effaced!! I am so excited to know we are progressing well. (Update 6/10) I lost my mucus plug today!!
For those due, are you dilated? How much?
For the first time mommy's, how long after losing your plug did you go into labor? Couple hours? Couple weeks?
