When is the best time to take a pregnancy test, how soon can I take it, and when does it become positive are among important questions to ask when trying to conceive. A pregnancy test, no matter if it's blood or urine, only becomes positive after implantation when the fetus has attached to the uterine wall and connects with the mother's blood system. Implantation, when the fertilized egg implants into the endometrium, happens about 9 days after ovulation and fertilization (range: 6-12 days).

The best time to take an at home test is first thing in the morning and with first morning urine because that's when the urine is most concentrated and has the highest level of the pregnancy hormone hCG. Try not to get up and go to the bathroom during the night and then do the test as soon as you get up
