Iud removal and regular periods??

Chelsea
For those of you ladies out there that have had an iud in the past. How long did it take you to go back to regular cycles? 
After I had mine removed it took 5.5 weeks to have a period. Today is supposed to be the start of my next period according to glow but it hasn't started yet... My boobs are slightly sore which is unusual for me. But I took a test yester just to see and it was neg... Any thoughts?
