Liletta

KRB
I just got my Liletta yesterday! 
It definitely hurt, it was like a big cramp then an intense pinch. I'd describe the pinch as a similar feeling to when I got my rook pierced. I'm still experiencing some intense cramps. I was hoping they'd go away by now. 
But my question is, do any Liletta users have any experience getting cists? I've heard that IUDs do carry that risk. I was wondering if anyone on here has had any and what happened? 
Also, the strings seem super long to me. They aren't sticking out like a tampon string but they're longer than I expected, I'll probably be getting them trimmed soon.
