22 day period

Emma

I just got the iud about a month ago now and I was wondering if this was normal. I have been bleeding for 22 days. For the first 11 days (still longer than my normal 5 day period) I had excruciating cramps with a medium flow which seemed to start treading to the end by day 11, but nope. Instead I unexpectedly bled through my shorts at a kohl’s. So days 12-15 still had pretty bad cramps and everything was like a very low flow but then it got thicker and more of a shitty color towards days 16-22. My next period is suppose to start in 13 days. Wtf am I suppose to except?
