Is this normal?

So I have my iud inserted November 19th. My first period started November 30th and ended December 10th. Which is a lot longer than a normal period for myself as mine only last about 3 days. But I figured extra bleeding would be normal.

BUT my second period started December 27th and has not stopped! I don’t know if this is normal at all.. I don’t know what to do since I’m soooooo tired of wear a pad or tampon and being uncomfortable!
