Period on Mirena

Has anyone noticed that their period is different on their Mirena? This is my second period and it's just..weird. I got really sick yesterday and this morning, almost flu like, started this afternoon, but it's like...light pink and just weird. Like...I don't wanna say crumbly but it looks like crumbs. Like itty bitty pink crumbs. I'm not having any pain or anything, but is this normal for my period to do this? It's never happened to me before. Thanks in advance!!
