Weird CM?!?!

I’ve been on the IUD for almost 3 months now. When I first got it I bled for 3 weeks straight and my periods have been super out of whack since. They have been coming about 15 days later than when they’re due. Today marks 15 days late yet again. All period symptoms but no blood. I just wiped and there was a slightly pinkish color. What is this? Could this be my pseudo-period?
