Fiber One Bars and Bowel Movements Or Fiber One Brownies

I'm 3 weeks 2 days postpartum and I'm still haunted by hemorrhoids and a 2nd degree tear that's pretty much healed, but still bleeds a little when I poop. I've taken stool softeners and they just aren't doing the trick, I'm breastfeeding so I can't take laxatives. So I was wondering, do fiber one bars help you poop? Or fiber one brownies? Does it make your poop softer? I've tried everything.
