Liletta back pain

Hi all!

I had a liletta IUD inserted October 25th and everything was going really well until 2 weeks ago. I’ve been experiencing terrible lower back pain when I wake up in the morning. Now, I have no idea if it is from the IUD or something else. My back only hurts when I am standing. My period is also a days late this month. I know the IUD is supposed to lessen my flow, but I didn’t think it would cut right off like this. When I had the mirena, it was more of a gradual decline.

I’m wondering if anyone else has any similar symptoms while on liletta.

Thanks!!
