Been losing my plug for 2 weeks

I started losing my plug at 36 weeks and my doctor says at that point it doesn’t regenerate. I’ve been losing bits and pieces over the last 2 weeks and will be 38 weeks tomorrow. I’ve also been having period cramping over the last few weeks. How much longer can I continue to lose my plug if it’s not regenerating anymore? Anyone experience this? Could I still go another week or is labor in the very near future??
