Hang in there!
I have heard that stress can cause babies to want to stay in a while longer. Losing the plug is a good sign for most - I'm routing for you! I lost mine more than 2 weeks ago, though - so either I've grown it back by now and will lose it again, or it doesn't necessarily mean labor is impending. Dunno. Everyone is different!
Sending birth vibes your way,
and hope for some rest from your stress!
