Does anyone else get late periods often?

Ashley
Can anyone relate to the fear of pregnancy ??? 
I've had a copper IUD for the last 3 months -
My first period was two weeks late, but my next two cycles were on the DOT according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>! But this month I am four days late so far, 
Someone tell me I'm not alone!
