CAN ANYONE HELP

Hi Everyone,
I had unprotected sex with my partner this month and now my period is 3 days late. My period is usually always on time and when it was a day late i decided that I should take a blood test It came back negative....but my period is now three days late could i still be pregnant or is it not possible? Any advice

I had a false negative on a urine test in the doctors so yes it is possible. I was about 5 weeks at the time.  Ive also heard that blood tests can be wrong when its too early.  It is more likely that your period is late and your not pregnant.  I think it is extremely rare that blood tests are wrong
