Heavy bleeding after iud removal?


I got my iud taken out on Wednesday after having it in for 2-3 years. Wednesday and Thursday I was spotting some, not bad at all. Dr said spotting would be normal. But starting Friday and now today Saturday I’m starting to bleed a lot. I had a pad AND tampon in today and after 2 hours I had already bled thru both. Now I’m making sure to change out my tampon every hour. Has this happened to anybody else? Is this normal after iud removal? How bad should it be before I should go to the dr?
