Tubectomy suggestion. For pregnancy?

Hi doctor, This is Renuka 31 years old. I have a baby boy age 5years old. In 2020 feb I was aborted through pills and again in nov 2022 and April 2023 I was aborted through MTP. As I'm having some depression pills from 1-2 years so we got aborted the babies. I was having severe throat infection and lung infection from past 10 months with cough fever and breathing issues continuously . I was also identified with cartilage damage in left knee. Iron deficiency and vitamin b12 & d3 also. Totally my immunity is very weak and I'm continuously having throat infections, fever, cough and severe breathing issues. So due to my health issues I don't want another baby anymore, so can I have permanent surgery for pregnancy? My doctor is not suggesting me for the permanent surgery, she's says to do copper-t, so please suggest me a good solution for my problem..
