NOTHING is helping 😢

No

My baby girl has such bad constipation. It's not leaving her alone . I even took her to the doctor and he gave her mineral oil ( attached pic ) to put in her milk so it can help help. I've been giving it to her for 4-5 days now and she still in pain. She even bleeds. Her butthole is so swollen and red. I don't know what else to do. I change her diet, give her fruits and healthy things, and it still doesn't go away. I hate seeing her in pain everyday, sometimes even 2-3 times a day as she tried to poop. I'm feeling so overwhelmed. By the way she is 13 months!
