Too many tests...: If a woman is healthy and fertile, with regular periods, she should wait until after she misses her period, and then bring her over-the-counter pregnancy test to the doctor's office. Then she can do both the otc test and the doctor's office test at the same time on the same urine sample. That should settle any doubts, and reassure all involved.

Blood test for HCG: 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.
