Everyone and every pregnancy is different though, so it's completely normal if you don't lose it. Also, if you do it doesn't necessarily mean labor is right around the corner unless you start showing real signs of labor.
Some don't lose theirs until they actually deliver. I never lost mine beforehand with my first, this one though I lost it a week and a half ago
I lost mine at 32 weeks with my first...I was overdue with him...haven't lost it this time yet.
