Kyleena - period stopped

So I got Kyleena back in November and I've had very regular but light periods every month since then. This month I had some period cramps but no actual bleeding. Did any of y'all have regular periods for a while and then they just went away or should I be worried? I know some people's periods stop on the iud but I thought it would be more gradual. My bf and I use condoms or pull out. Thanks guys!
