This may not be the answer you’re looking for, but personally I wouldn’t want to resize it multiple times, I would just wear a reasonably ok looking fake until I settled on weight I thought I’d stay a while. I personally got a fake ring (silver with simulated gems) in similar style to my engagement ring in the size I planned to resize it before I realized it to make sure the new size would fit comfortably and not slide around. I still use that ring regularly when I’m out places I worry about damaging or losing my real ring.
