Pregnancy unlikely Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for 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

Wth the information provided, ovulation date cannot be accurately determined. With a "25 day cycle", you should have ovulated on 10/9 or 10/10, and a home pregnancy test may not be positive prior to !0/24 or 10/25, so wait a few more days, and obtain a serum HCG test to be certain about pregnancy.
