Can Hersheys chocolate cause you to go to the bathroom?

I am serious, so don't respond with an immature answer. I usually eat Reeses and the other day my mom bought Hersheys. I have been eating like half a bar a day for two days now. Both times that I have ate the Hershey chocolate within a hour I had to go. Why is this happening? It is not painful or making me sick but is just weird....
