Hey, best wishes for you by the way! I'm 10 days overdue today.... don't think i need castor oil though since everything has been emptying itself out like crazy

About the discharge, thought i'd mention that over the last few weeks i've lost tons of large firm pieces of mucus, but starting this weekend i have on and off had a stream of liquidy mucous coming out, like you said, enough that you need a pad. Lots. it is definitely discharge not amniotic fluid or pee though. last night i just sat on the toilet and let it come out for awhile.
So... i don't know..... but hopefully it's a good sign cus i want my baby out now!
Good luck to you!!
