Will I drop more on the right? Should I have gone bigger than 275 cc on the right (went 250cc on left)? (photo)

You look much more symmetrical than pre-op.  In your posted photo, you are not standing straight and that makes the post-op photo look more asymmetrical.  Best,

In my own practice I tell my patients that it
will be about three weeks before they even believe that they're going to
come down, by about 12 weeks I will know and you will know you are high,but no
one else will care, and ultimately your most natural result will come
between six and 12 months after surgery.

Some patients can take longer to drop than
others depending on the size of the implant and their anatomy. For
example, it will take longer for a 500 CC implant stretch and relax the skin
and muscle than a smaller implant. A more muscular person with a sub
muscular implant will take longer for the implant to drop as well.

Share your concerns with your plastic surgeon,
who I suspect will walk you through this and confirm that your normal.

It is very early but thinks look very nice and natural. I think you will have a great result you will just have to wait a little longer for everything to settle

It takes at least 2-3 months for the implants to completely settle so I recommend giving things more time. Certainly your asymmetry is improved from pre op and you will just have to see if more volume is needed in your right breast.

It is still too early to judge your result. It is going to take several months for the implants to settle and to know their final position.I would keep following your plastic surgeon's instructions and alert them to your concerns. The difference between a 275 cc and 300 cc implant is minimal, so going with a larger implant would not have made a big difference.
