Stop looking at the scale for 1..
2 do NOT train everyday..
Go go to a 5 day weight based training to continue building a nice muscle base , that's what is going to keep the figure, And hold you throughout , this should happen with good carbs and protein consumed 30-60 minutes prior ...
I would back off on the cardio completely for a coupled weeks other than 30 minutes 3x per week walk for health...
Then start adding in some hiit cardio once calories , cardio, and new routine are situated.
Just my personal opinion, you've done a great job, but sounds like you need to reset not shock
