sex while ovulating on Skyla

Hey all! I've had my Skyla IUD for about 2.5 years but I've always been careful to also use the pullout method. I keep track of when I ovulate so I have a sense of what my body is up to and my body was at peak fertility according to the tests the past two days. During these days I had sex and the guy I've been sleeping with finished in me and didn't pull out. I know Skyla works in other ways, not by stopping ovulation, but am I still just as protected during ovulation or am I pushing the limits of my IUD? Any advice would be much appreciated!! Thank you! :)
