Do gps do iud insertions or do i have to see a gynaecologist for that?

Maybe: Whether or not your local GP would do this procedure & charge differently for the effort is unknown. You would need to contact the office crew of one or more to see if they offer the procedure & at what cost. It is not a difficult procedure if you have the training & equipment, but the procedures & billing practices in your country likely differ from those here in the USA.
