My Charlie currently has pin worms and I cantell you - they do not just go away. They are small and whiteand sometimes you will see some ontheir poo, and often youwill see them on their tail/butt area if you pick them up and look atnight.
Some days you will see none, and others you will see tons. Ifyou are sure you saw a few one day, you may not see any for weeks butshe still has worms - they live in their gut and you only start seeingthem when the infestation is in higher numbers. Take her poopto a vet who can tell you for sure if she has worms because you willnot always see them.
The female worms will continue to lay eggs and Sunshine will keepgetting more worms untilshe starts loosing weight... if yousaw worms, take her poop to a vet please.
