How accurate a negative home pregnancy test if taken 8 weeks after last risky behavior, following instructions. stds are not a concern?

Reliable: The results of a home pregnancy test done 8 weeks after last sexual exposure should be reliable. if there is doubt about the timing of last sexual exposure, the test should be repeated.

Very accurate: risky...is not a wonderful term when referring to sexual behavior. Simply: condoms PLUS BC pills or spermicidal gel, foam, sponge, diaphragm or spermicidal insert. No logica at all to have risky relations.Get checked for pregnancy.

Very accurate: 8 Weeks after sexual intercourse is more than enough time for a pregnancy test to show if a woman is or is not pregnant. Take care.
