IUD & Sex

I had my Kyleena IUD inserted August 2nd. Yesterday, August 11th, I had condomless sex. Should I be protected? I know with Kyleena IUD theres less than 1% chance of pregnancy, I'm only concerned because they told me to wait to have sex without a condom for 7 days (Just like Birth control pills) and I feel like I had sex too early although I waited 9 days.
