Could this be picking up pregnancy?

I'm 6 dpo and 6 days ago I got a very positive ovulation test which I made sure to BD. Since then I've taken a few more ovulation tests just for the sake of it and there has only been one line obviously not ovulating.. But today I took one and there's two lines and its like its getting stronger towards ovulating again. Is this due to ovulating twice?? Or picking up baby hormones? 
Today's ovulation test.. 
Last weeks ovulation test..
