Bowel Movement 3 weeks 3 days postpartum?

I've already had my first postpartum poop and second, and third. Now I'm 3 weeks 3 days postpartum and I've been eating fiber one brownies and popping stool softeners religiously and NOTHING... everything seems healed but I'm so scared that I'm going to 're rip' myself down there even though my stitches are gone. I'm breastfeeding so I'm scared to take actual laxatives.... What do I do? Has anyone ever had this happen to them before? It's like ever since my stitches healed it's harder to poop.
