IS THIS POSSIBLE? Help

It’s not really a big concern but can you be pregnant and still get periods on the Kyleena IUD? Just asking because I saw a previous post and nobody had answered. Had sex on the 16 of September, my period was late by like 6 days (this is only my 3rd month with Kyleena) then I got my period on the 6th of October. My period is on day 9 and hasn’t necessarily been light yet. Is that even possible? I don’t have symptoms but is it possible to get a period with an hormonal IUD and still be pregnant?
