5 days postpartum - pain in rear

My LO was born 5 days ago. Sorry for the TMI but I am seriously in pain and not sure if this is normal or not (didn’t happen with my first). I was able to poop fine at the hospital (it hurt a little but I could go). Since I’ve been home from hospital (Saturday) I feel like I need to go but literally can’t and I am bleeding from my rectum. Dr said I could take stool softeners and miralax but neither has helped so far. I’ve been eating balanced meals and even extra fiber to try and help. Is this normal? Any advice? Thank you.
