Confused, bowel movement normal?

I recently got my IUD inserted(Minera) on the 11th of this month. I didn’t start spotting till the 13th. I’ve been spotting some days and light bleeding some days since than. I thought I was done spotting on the 20th but than started spotting again the next day. (Today) Yesterday I started getting cramps but it was bowel movement. Has anyone else had a change in there bowel movements when they got the IUD? It felt like diarrhea, because I went twice yesterday and again today. If this is normal, how long will this last?
