I for shur ovulated around the 13th and 14th, somewere around there and i had sex the 12th. Im asking how long should i wait or what should be my pregnancy signs if i did concieve?

In how many days can I trust the pregnancy test?

What was the story behind the official adoption of the ancient planetary names for the days of the week in 19th century Japan?

My friend had a blood pregnancy test done 7 to 8 days after possible conception and the result came back negative. She is still having pregnancy symptoms. She asked the lady who gave her the results and the lady said that the test should not be done until atleast 10 days after conception to be most accurate. How accurate is a pregnancy blood test 7 to 8 days after conception? Thanks in advance!
