On the 14th day of cohabitation, I used the David early pregnancy test and it showed negative, so I wasn't pregnant.

Patient's question:

No

Doctor's answer:

It is recommended to wait a few days before testing again. The start of pregnancy can be determined by several methods. One is to detect the hormones produced by the newly formed placenta. Clinical urine and blood tests can detect pregnancy 6-8 days after conception. Home urine tests usually take 12-15 days to be effective. A pregnancy ultrasound test can show a gestational sac around 35 days.
