Pregnancy test : Home pregnancy tests are very accurate. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. ...Read more

After missed period: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce 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. A negative result on a test done too early is not reliable. ...Read more

Can I trust the result of a home pregnancy test ( from first mornin urine) after 10 weeks of intercourse? I know I should but im still suspicious.

Can I trust the home pregnancy test which was taken on (26 July) 31 days after intercourse? Result was negative and there were no symptoms.

Can I trust the home pregnancy test which was taken on (26 July) 31 days after intercourse? Result was negative and there were no symptoms.

Yes: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed. ...Read more
