Hi i'm 12 days late and done a pregnacy test 5 days ago and it was negative, could i still be pregnant?

It is possible.: I think you should take another test. If it's still negative, you might want to contact your doctor for a blood test. Some women have trouble getting positive results on home tests when they are, in fact, pregnant. I don't know how common that is, though.

Sure: You should repeat the pregnancy test. You took the pregnancy test about 7 days after ovulation and it could take up to 10 days for a pregnancy test to become positive. Repeat the test.
