4 weeks pp

My stools were normal the first 2 weeks. Now they start out hard and painful, then the rest of the stool is normal. But it like tears me and causes bleeding. I use Tucks pads. I drink water like crazy. I eat cheerios for breakfast every morning and eat veggies during dinner. My diet is fairly healthy. What do you think I should do to make my bowels normal? I dont like fiber supplements or fiber snack/cereals as it all makes me super painful/gassy. At the hospital they were giving me some sort of laxative type pill. Dont remember what it was.
