Good evening.. Yes there are 2 types of copper T , 5 years and 10 years . It depends on which type was inserted for u. As it’s been 4 years , get it checked once to see if it’s in position . If ur able to feel the threads that good .. no need to worry . Otherwise get an X ray to see it’s position It’s not an emergency, once pandemic settles down u can get it. If ur not sure 5/ 10 yrs which one they inserted . Can get it removed after few months and get reinserted a new one .
