Should I have sex today too? Or is it over?

These are my ovulation tests the last few days and the hearts are when I had sex. I wish we would have had sex on the 2nd as well but my husband is in grad school and this week he was busy with projects and finals that we just couldn’t make it happen time wise. Do you think there is a good chance I could have gotten pregnant? Since the test was negative today does it even matter if we have sex today? Just wondering! We’ll see what happens in two weeks! 🤞
