Concerned with my IUD

hey guys, before i jump into my whole issue, i’d like to say that i am an extreme over thinker and experience very very bad anxiety- so if you come across this post, please put your two cents in!! i’m 17 1/2 and about to graduate high school. i’m very little, i weigh about 88 pounds and i am scratching the surface of 5 ft.

i got my iud inserted in august of last year. it has done wonders for me as i used to have periods so bad that i would have to miss school a lot and would just scream in pain the whole time. with this whole corona virus thing going on, i know we are all stressed. i know my thyroid is also being watched.

so the problem is the last time i got my period, i had it for 3 weeks. the first week it was spotting and i didn’t really have to use a tampon or pad. then came the real deal, then back to spotting. the spotting at the end was fine. (i’ll post a picture of my cycle!) i just started spotting again and i am afraid that it will last three weeks again. i am just wondering why it lasted that long, if i should be as worried as i am, and if there is anyway i can induce my period’s blood flow?

please help!!
