Talk to Gynecologist on Ovarian Cyst

Hello doctor, I hope you are healthy My name is Nasrallah, I am from Kabul, my wife is 48 years old, she has given birth 8 times, 5 girls, 2 boys and 1 boy died. She has been suffering from ovarian cyst for more than 5 years. The doctor had advised her that she should get pregnant to heal the cysts But after the child, who is currently 5 years old, she is still having casts, she always takes medicine, but she does not get better, her monthly period is very heavy and she bleeds more. Blood pressure, hearing loss, and poor eyesight have been reported as a result of overuse of drugs I don't know what the main problem is, can you guide me
