Some ways to help baby?

My daughter is 13months old and the last week she has been having really hard poops 💩, so hard she can’t get them out, I have to help. It’s also causing bleeding inside her bottom. She has a doctors apt tomorrow to check and find away to help her. She literally screams and cries for 30mins to an hour trying to push it out. The doctor kept saying apple juice or prune juice but hasn’t helped. Is there anything else I can do without using meds until I can see her doctor tomorrow?
