Need help

My boyfriend and I had sex during my expected ovulation week but he pulled out. But now it’s 2 days past my expected period and I still haven’t bled. I took a blue dye pregnancy test yesterday as well as a pink dye and the blue showed more of a line than the pink but I a still haven’t bled. Could he have gotten me pregnant with precum? What’s happening?

In the picture is the blue pregnancy test. I don’t have pictures of the pink, but the test said not to wait longer than 10 minutes and I waited 3-4 minutes. But the pink dye pregnancy test was a really cheap test. So I need help.
