IM FREAKING OUT

 I haven't had sex since before my last period. My periods have been regular. Always come the 5th day of sugar pills.  I just got off the third period two weeks or so ago since my scare in Feb.  And use birth control pills correctly, use a condom, and also pull out wearing a condom. He never ejaculates inside of me. My BF also had two undescended testicles as a child and is highly likely to have fertility issues. We always check the condoms before during and after sex. After sex, we fill the condoms up with water to see if they have broke. So far, none of the condoms have broke. No water ever leaked out.  I've taken 6 pregnancy test and all day negative. I haven't had sex since April 22nd. My period started the 26 and ended the 30. My next period is May 24. Am I pregnant?
