Hi, I Was Playing With Myself 3 Weeks Ago And

Hi, I was playing with myself 3 weeks ago and i put some marbles in my butt i think that there were 4 but im not sure. i got them all out but i was scared that there was still one in there. I had some abdominal 2 days after, but that could be a flu because my mother got it the day after. I want to know really really sure if there is any possibility for a small marble (2,5 cm) to get stuck in there. I can't feel anything when i put my finger in it. Like i said it was 3 weeks ago but i have a lot of anxiety. Please answer my question.
