Ah sis, normal lang yan! Kapag nag-insert ng contraceptive, may slight irritation kaya lumalabas ang white discharge, it's your body's way of reacting sa insertion, kaya ang itching ay malakas na expected. A few of us sa group namin nag-experience ng same thing, and it usually settles down after a few days to a week, pero kung hindi kumuha after that or sobrang intense, definitely check with your OB para sure walang infection or improper placement.
