To deworm again or not?

I am a new kitten owner this is my first kitten and her name is Vada. I got her at 10 weeks old she was born in September and when I got her I went to fleet farm and got the dewormer as my mom who has had many cats said to do and followed the directions and treated her right away, which was towards the end of November. Today I got home and in her dish looked like a round worm should I deworm her again or is this just her flushing them out this late? 

She's not flushing worms. You need to take her to the vet and get a specific dewormer for round worms. She's got a bad infestation. There are so many worms in her that they have migrated to the stomach where she could cough them up.

That is what I was worried about but since I found it so late this evening the local vet is closed until morning. Thank you! I will get her in tomorrow!
