Is something wrong with my IUD?

So I’ve had the Lilletta IUD since April 2020 and haven’t had a period since August. I’ve had some spotting since then but it only ever lasted for a day. Now the last 3 days I’ve had crazy spotting and all the symptoms of my period back (bloating, cramps, nausea- everything that caused me to get the iud in the first place). Does it sound like I should get it checked to see if something is wrong or is this normal sometimes?
