Had unprotected sex several times with my bf, now my periods is 2 weeks late, i took home pregnancy test few days ago twice, but negative. am i pregnant?

Possibly: If your pregnancy test a few days ago was negative, it's possible that you are pregnant. The answer would depend on when you ovulated. Typically, a woman ovulates sometime between 9-14 days after the first day of her menstrual cycle, which was quite awhile ago if you are regular. Though most common, some women ovulate at times outside the norm.
