None of those things will prevent implantation. They won't slip out, you can't push them out and you can eat all the hot soup you want. And you don't need to lie still for the next 12 days either. Actually moving around like normal would be better for your circulation.
Don't take any ibuprofen, advil, and stay out of hot saunas and hot tubs as you don't want your body temperature to get too hot. But you can move around and eat normally.
I'm keeping my fingers crossed for you and wishing you luck!
