One Breast Implant Taking Longer to Drop

I am three weeks and 2 days post op under muscle Mentor smooth round moderate profile saline implants of 225 cc filled to 250 cc. I was a full 34B but 41 years old and trying to fight gravity. My left breast implant has been sitting lower since week two and feels almost like it's not there (I mean it's beginning to feel like my own). My right one still looks close to where it was when I came home, and always feels like it's trying to go up further especially when I bend over to pick things up or pet the dog. I was told to only start massage at my two week mark which I have been doing religiously. Why is the implant placed so high in the chest area in the first place when getting sub-muscular implant? I am really concerned that the pocket was not made wide enough on the right and won't drop because it can't. I am constantly wondering if I should use my arm as I normally would or if I should try to use it as little as possible. Should I wear a strap or go braless? I chose my plastic surgeon because all of the pictures on his website looked so natural. I did not want to look like I had implants. At the moment, I look like I have something shoved up into my chest on the right side. It's ugly! I am going to Hawaii with my Mother in Law in two months and can't even go bathing suit shopping. PLEASE HELP!
