Bleeding after Skyla IUD removal

I had my IUD (Skyla) removed on 2/14. I had it in for 2 1/2 years and had a period every month. Well I didn't bleed at all after removal until 2/18. I have been bleeding since. (Med-heavy bleeding with some clots) I'm just wondering how long others have bled and what is normal? I thought it was going to stop on Friday but then by the evening I started to bleed heavy again. According to this app I was at the end of my fertile days when I had it removed. But with all the bleeding and clots I'm not even sure if it's still possible to conceive? Can anyone give any insights or their opinion?
