Does old caesarean section collection affect fertility?

Question
Hello doctor,
I am 34 years old, had my first cesarean section, my baby is 30 months old. My husband and I have been living normally for about a year without using any contraception. However, I have not conceived yet, my age is quite advanced, so we are also expecting a second child.
About 1 year ago I noticed occasional abdominal pain and a little brown discharge after menstruation. So I went to the hospital. The doctor did an ultrasound examination and said the brown discharge was due to the old caesarean section still leaking from the inside. At that time, I did not intend to have a second child, so I did not ask deeply about this issue. Until now, I'm looking forward to the second child but not pregnant yet. After giving birth to the first baby, 5 months later, she had her period again. Every month is just a month with a difference of a few days. The amount of menstrual blood is now less and less, the 3rd day is almost clean. Then around the 9th, 10th day of the menstrual cycle, there is a little dark brown discharge. Every month so far. Doctor let me ask if the accumulation of fluid from the old caesarean section affects the ability to conceive? Hoping to get an answer from the doctor soon. I would like to thank the doctor.

Simultaneously remove all foreign objects, burn the mucosal surface and abnormal blood vessels, cut off the lesion margin to thin the edge of the scar.
