Help with stool problems!?

So, I usually go number 2 when I get home, everyday around 4ish. Today, I stayed after school to workout, and earlier I did my usual conditioning cl, I came home and found very hard to go, so I took a shower and tried again, no luck, I've tried 4 times now and I took a stool softener, I was wondering if it was possible to push so hard you hurt yourself.
