What are you measuring ?

Went to my 37 week appt ( I am 37+2 with my 3rd ) and got my pelvic exam to check to see if I'm dilated and how effaced I am. Well surprisingly I am 3cm dilated and 50% effaced. My plug has already fallen out and baby boy is pretty low (even had some blood tinged mucus today) . I'm super excited to meet my little boy but I'm pretty sad that this pregnancy is gonna be over soon. What are you ladies measuring at ?
