If i had unprotected sex 8days ago will i be able to tell of i'm pregnant though a home test ? and a blood test ?

Probably not: Usually takes 14-20 days for it to show up on home test... Blood test slightly more sensitive.

After missed period: Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
