Am I pregnant?

Hi everyone, I’ve been practicing safe sex my whole life and two weeks ago my boyfriend came in me 3 days in a row when I was ovulating. During the first week I was cramping a ton and they randomly went away. I took pregnancy tests (the one that is able to detect 6 days before your period) and it was negative. I am expected to get my period in a couple days, which would be almost 3 weeks since he came in me. Do you think I am not pregnant? Should the test have said yes if I was or is there still a chance?

Still waiting to see if I miss my period but I am doubtful that I am pregnant.
