Lots of spotting and no period?

April

Hey ladies. I have an important question and maybe someone could help me out a bit. So i recently got my liletta iud (11/03/17) and I’ve had a lot of spotting and no period. I’d get cramps but i didn’t have much of a heavy flow which is normal for me. I just want to know if this is normal. Thank you to anyone that can help me 😊
