when is the earliest point that a pregnancy test can be taken, thankyou

[quadrophenia]

not for me, i have an anxious friend, and four kids later, i don't bleedin know

3 weeks from the last episode of unprotected sex is the most reliable test, although some will show up as soon as 2 weeks (maybe sooner?). However if the earlier test showed up negative, i wouldn't believe it to be 100% reliable until 3 weeks after the last sex.

thanks much appreciated
I love MN it makes me look clever!!

The early ones (like first response) that say they can test 4 days before period due are based on you testing 10 days past ovulation. (they assume a 28 day cycle with 14 days between ovulation and period) but tests may not show positive that early even though your friend may be pg.
Good luck
