Period or Pregnant

Leslie 🐚🌻 • • 21 • Virgo •
So.. My period was about 12 days late. A couple of weeks earlier about a few days after ovulating I was bleeding sorta.. More like dried leftover brownish blood.. That lasted for three days. So from then until today I thought I was pregnant.. I haven't taken a test yet but I did get my period today. Or so I think. Is it possible to just bleed and still be pregnant ?  
My periods usually are always a few days late. But never as much as 12 days. 
So what do you ladies think?
