membranes and mucous

Yesterday I had my membranes swept at my 39+4 appt at around 11. 
I had bad cramps all day long and some contractions, but they stopped when I went to sleep. 
Woke up this morning around 5 and went to the bathroom and had lost my mucous plug. 
Now I've been up doing random things since and I have cramping again and what I think are contractions. 
How much longer until labor if anyone has experienced this/ or has any input after getting their membranes stripped and mucous plug lost?
