IUD/BLEEDING

Emily

At 5 weeks pp I stopped bleeding for 1 week. At 6 weeks pp I got an iud and the day after I started bleeding again and haven’t stopped since (just hit 12 weeks not bf at all). Should I be worried or can I expect this to end soon?? It’s really annoying being a little bit a couple times a day. I get excited thinking it stopped and then all of a sudden!
