One day period or Pregnant?

Dana

So my average cycle is 33 days and I usually bleed 3 to 4 days. This last cycle, hubby and I were baby dancing during ovulation but he pulled out...

However, on the day of my expected period, I did start bleeding - but it was very light and only lasted one day. I didn't really think anything of it but now I am curious... Has anyone had a short one day bleed ing and ended up being pregnant or it was just a super super short menstrual cycle?

I am pretty sure it was just an irregularity in my cycle and it was in fact time for my cycle but I'm just curious if anyone else has had this happen?
