Weird period..

Hello. ! I had an IUD placement in August of 2019. Since then i have only had 2 periods, the first one lasted 3 weeks with major cramping and clots.

This time I've last a few days shy of a month. At the beginning cramps were fierce for about a week and a half, then the following week was crazy cramping, bleeding and some pretty big clots. Anyone familiar with this situation?

Also, i am waiting for my insurance to start again so i haven't been able to go to my dr just yet.. TIA
