It's still pretty early for you to be taking a test, wait about another week and take a test, and yes blood tests can detect pregnancy early, but not this early, if you were pregnant you'd be right in the implantation stage, in about another week you'd most likely get a positive, good luck!
I have seen a doctor and the pregnancy test proves negative,I have also used series of pregnancy test kits they were all negative as well.... Will I be right if I say a pregnancy blood tes can detect an early pregnancy? Thanks so much for your reply.
Having unprotected sex at anytime can lead to pregnancy, while most women ovulate about 14 days after the starting day of their period, it varies from woman to woman and cycle to cycle. I would wait until your next period is due and take a test if your period doesn't show. Also stressing about it can cause a delay in period so I would just relax and see what happens! Good luck!
