Kitten has roundworms

My kitten received her second dewormer yesterday with no signs of worms. Today she had a worm in her stool.

thankfully I had taken her stool in yesterday to be tested and just got a voicemail that it was roundworm. The vet said to bring her back in two weeks for a second dewormer. Unfortunately they closed when I saw the message (couldn’t have my phone at work).

Should I do anything in the meantime?
