how soon after conception can a pregnancy test be positive
A positive test result is almost certainly correct. If you do a pregnancy test on the first day of your missed period, and itâs positive, itâs probably about two weeks since you conceived. You can use the pregnancy due date calculator to work out when your baby is due. A negative result is less reliable.f youâre not sure when your next period is due, you can do a pregnancy test 21 days (three weeks) after you last had unprotected sex.
