Mucous plug

Can somebody shed some light on why im continously, days in a row losing more plug stuff ? Nothing else is happening so why is there so much coming out if labor isnt starting? Its day after day, saturday was a HUGE amount compared to the first few times. And every day since and a few days before saturday, im losing bits and pieces and yeah. Like whyyyy is all this coming out right now?

Yesterday sitting down to go pee, I heard/felt/seen a glob fall into the toilet...

This is my 4th baby, i know they can regenerate. Im 36weeks+5 days. Due in 22 days
