Soaking too often can stress the snake and cause difficulty when shedding.
When the snake is in shed, their bodies are covered with a layer lf milky lube that helps loosen the skin. Soaking them will prevent the lube from performing it's duty.
If I were as worried as you seem, I would give a nice warm soak to encourage her to poop. This practice is used for a lot of reptiles it seems lol..
