Implantation Question

Lynzee • Mommy to Ammarie, born on March 3,2016!
This might be a stupid question, but it doesn't hurt to ask! 
Is there anything I can do to help a fertilized egg implant? I'm 5 DPO, and I know that if I did conceive, implantation will be happening in the next few days. 
Anybody have an idea? Like, I know the old wives tales so to keep warm and try to stay still. Does that actually work? 
Just curious. :)
