5 weeks late and two weeks of spotting?

Kelsey • TTC since September 2014. ✨✨✨👶🏻✨✨✨
I have a fairly regular cycle (not totally regular though) averaging 31-32 days long, and I am currently 5 weeks late... I have completely missed periods before so when the pregnancy tests kept coming back negative I figured that's what was happening again, so I assumed it would start when my next one was due (which would of been a week ago). However instead of a period I started spotting a few days before AF was due and spotted for almost 2 weeks. Could that spotting have been my period? Has anyone else had this happen? Thoughts please!
