Diagnosed with secondary endometriosis over the ceasarean scar

I had baby 7 years ago via Caesarean section. After 2 months of CS I started to have pain over right side of CS scar. They did USG that time nil issues noted. I had pain on and off. Just recently 1 year back, my GP diagnosed ? Secondary endometriosis over CS scar as USG showed subcutaneous fat over the scar. I have visited Gynaecologist and she told me to conceive baby and will remove during my 2nd Caesarean section. My GP and gynaecologist has said it’s secondary and does not affect fertility. Does anyone had endometriosis over Caesarean scar?? Any fertility problem?? Also after you get pregnancy, does scar part hurts or not??
