Maybe it'll be soon? Bloody show (no pic!)

Gen
Hi, 
I'm 41 weeks today. I've been having cramps (like period pains), irregular contractions and mucus plug list over the last few days. This morning I had my bloody show and still cramping. 
Any guesses on how long after bloody show?
Husband is getting ready for work, I'm unsure if I should ask him to stay home....
Help!
