Longer Period from an IUD??

Nicah

Hey guys so I got an IUD inserted about 3 weeks ago and I am having my first period since getting it. Problem is, it’s been 10 days and I’m still bleeding. I haven’t had a period last this long before. The past 3-4 days have just been spotting though. And it’s more brownish than red at this point. I’m starting to get concerned. Andy advice for me?
