Hi @Chev, two weeks is still very early days and as @kmakm said, it can be a good six months or so before your new breasts are settled into place and all the fluid and swelling that happens with the surgery has gone. As you've also still got a drain in that does indicate that there is still quite a bit of fluid to get rid of.
After all we've been through having reconstruction can add a level of extra anxiety about whether we've done the right thing, how will the new breast/s look etc and I know I was second guessing myself quite a bit in the first few weeks. I'm now 5yrs on from my DIEP recon and am happy with how things turned out, although there were a couple of revision surgeries that followed the initial one and I also opted for nipple reconstruction down the track. Hang in there, hopefully you'll feel more confident with your new look in the coming weeks.
