I got my iud on the 25th of November and I knew I'd have irregular bleeding. But this is kind of crazy. I have rarely, if ever have had cramps with my periods in the past and now have been tempted to pull over to the side of the road because they make me lightheaded. I have a decent pain tolerance, so maybe I'm just not used to this kind of pain. But is the bleeding for this long normal for a lower hormone iud? I also took a pregnancy test just incase and it was negative.
