Skyla IUD

Bee • 👨🏻👩🏻👦🏼🐶🐶🖤
I got an Skyla IUD placed back in October and since then my now fíance --whenever we have sex-- doesn't pull out or use condoms anymore. Has anyone somehow ended up pregnant? This has been going on for about 3 months now and it doesn't bother me. I just want to know any side effects I suppose.
