OK, first off, the guy in me will speak. I'm typically into thicker women, but for a long lean body, you got a fucking hot physique kimmy. Great little ass for being so long and lean too. Don't see that often. Love the tats, and ever since Stoya took over popular porn, now I gotta thing for pale skinned hotties. So nice work lol
Now to answer your serious question.

Yes, it happens to us all. Did you take any diuretics? That is one thing that saved me from having a huge rebound is I didn't take any my last show. Although, you will still rebound no matter what, its just to a certain degree based on your body makeup.
As MM said, to recover you gotta just get back on the horse so to speak. I won't repeat what she said, but will add this.
Typically, at least for me and most of my former clients, you may gain or lose fat in different areas than you did before you competed. Why this happens I have no idea, but fat re-distribution does happen to everyone. For example, you may be used to losing fat from top to bottom. The next time it may be from bottom to top. No biggie, just don't freak out if it happens.
Bad thing about competition dieting (maybe not so much for a bikini competitor) is that it tends to have those effects on your body comp in regards to the next time you diet down.
Again, i don't think its a big concern, but some, especially women (happens to my wife everytime), have a hard time if that one area doesn't come down like their used to... even if others come down faster/better.
Again, very hot physique. Great job.
P.S. How tall are you?
