Breast Enlargement - to all the ladies that have had Implants under the muscle?

I have recently had surgery (10 days ago) - implants under the muscle - I was told I could take off the strap around my body 10 days after which I did and after a few hours the implants inside seem to be rising up! Has this happened to anybody and if so is it a case of leaving them be and they will relax eventually on there own? When they rise they look awful from the side view - i'm really quite worried. A sports bra doesn't prevent this happening either.

It's going to go back to normal on its own.
