Early ovulation?

So, I'm not basing anything off of two tests first of all. Just wanted to get that out there before I hear anything negative. I KNOW both of these are negative. Just have a question regarding possible early ovulation. For starters, I only have a 4 day period, so my period ended 3 days ago. I've always been skeptical of the fact that I might ovulate early and by the way my tests are going, I'm thinking I do. Does anyone else ovulate early after your period? Again, I know I've only done two tests so far so I cant really base early ovulation off of just these two. Theres just a bigger difference in these two that I thought there would be. Plus at this point, i figured i wouldnt get any test line due to just getting off my period. The top one is yesterday and the bottom one is the one I just took.
