Depends on how much you feed her.
Based on the amount of time that has gone by. It sounds like you are either not feeding the snake as much, or as often, as it wants to eat.
If you have the snake on a schedule (example 1x per week0 take the snake off any schedules and offer food 3x per week.
Also what size and age is you snake? A pic would be helpful or post more info.
