should I be worried?

I am five days late for my period. I have an IUD and my boyfriend and I go back and forth between condom and no condom depending on the day. My period is typically not reliable and may be a few days off, but I am not feeling cramps like my period is approaching. 
Should I be worried that I'm pregnant?
