Update!!!!! Late period!!!

Guys my period is 3 days late!!! I was on the IUD last yr and got it removed in December and it started right away...at first it would come earlier than what my calendar would say by a day or two then it would come exactly on the day according to the calendar...and last for 4 or 5 days...I this it's time to pee on a stick...what y'all think?
