Bled so bad

lia

So I got the kyleena IUD back in June and my periods have been on and off light and heavy but I was at my boyfriends and before I went to the bathroom I was laying down but I got to the bathroom and sat on the toilet and blood was pouring out of me like I’ve never seen before! Please help what should I do it’s calmed down now but I don’t know what’s wrong or if this is normal
