OVULATION KIT QUESTION - HELP!

Ke
Hi ladies! 
I am trying for a baby, I have just come off of my period on Friday and took a test that day - this come up with a O on the digital clear blue OT. I done another test on Sunday (yesterday) this came up with a flashing smiley! I have now done another one today and I have got another flashing smiley! So this means I have had a flashing smiley face 2 days after my period. 
Also I wouldn't even say I had a period due to how light it was, it was like spotting! 
Could I be pregnant? And the OT has picked it up? 
Help has anyone else had a flashing smiley two days after your period?
