what size pots are they? If youve just started 12/12 it probably isnt as much of a worry, but if you are repotting, do it ASAP because repotting during flowering can stress them enough to go hermie. Happened to me once. Since then, I am very paranoid and I do not remove the plant from the pot unless I either cut the entire thing off or cut the bottom off and set it in a new pot. air tools or a dremel make this a 3 minute clean procedure. saws are a little more difficult but ive done it.

if your not paranoid...then repotting a few days into flowering really shouldnt affect anything, just a some recovery time.
