Had sex the day after my period stopped. took a test 10 days later and it was negative is it likely that it was accurate at 10 days after conception? (2 weeks before period) i take bc same time everyday havent missed a day, started taking in augus?

Tested too soon. 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.
