Day 5 transfer with IVF...if this works, when should I expect implantation? THANKS!!?

how old were you embies? They transfered 5 day embies for me and told me to test after 8 days with blood. I heard with 3 day embies they make you wait 2 weeks. Also with 5-6 day embies implantation should take place with in 3 days after transfer. To be safe I have stayed off my feet for 1 week as much as possible and am not doing anything until after my test on Tuesday. Just spoil yourself as if you already are pregnant and think happy thoughts. I know it's a tough wait. I found a great website called www.ivfworld.com It's a great place to get awnsers and support.
