No, it made them really funky though, like one month I’d have a normal cycle, then a week later, I’d have brown spotting for a couple days, then two weeks later I’d bleed for only one day, then a couple weeks later I’d have another normal cycle. It was really weird, and I pretty much wore a pad the entire 6 months I had it.
I do have endometriosis though, so I wonder if that had anything to do with all the pain and cramping from the IUD. My body never adjusted to it; I could literally feel where the device was the whole time. It sucked.
