Spotting or Light Period

Jordan
Hey everyone so last month , I got an copper IUD while I was on my period , I finished my normal 5 day period and I had one free day but my period came back right after that for another five days . For the past almost 2 weeks , I've been wiping and seeing blood and its been ruining some of my pretty underwear 😩 I usually have a heavy period but I am wondering if the birth control has lightened my period or if it is just spotting , I'm confused y'all , help a sista out , please 😪
