Infertility after cesarean

Cherish
Has anyone experienced this?. If so what was the actual reason for it and has anyone concieved after experiencing this?? And how did you accomplish it??... So I have two children from a previous marriage both were born emergency c section as I had severe preeclampsia with my first child, she was born at 29 weeks gestation. I went into labor at about 37 weeks with my son, so of course, in order to prevent rupture another emergency c section. After the birth of my son and ever since I experience extremely painful periods...My son is now 7 so I have not conceived in about 8 years. I am 32 and I am starting to think I should leave my fiance so that he can have children because every month is so heartbreaking. I desperately want this baby. I have not had any type of fertility testing, I think mostly because I am afraid. My fear is that whatever is causing the infertility is permanent or very costly to fix. Perhaps this is irrational.... Please anyone experienced infertility after Cesarean that can offer some feedback??
