No, it's not possible for a test to detect pregnancy that early. Your body's not producing enough of the hcG hormone (aka pregnancy hormone) to be accurately read by a home test. Not to mention, it takes at least a week for the fertilized egg to travel down the fallopian tube and implant itself in the uterine wall. You'd have to be at least 4 wks pregnant in order for you to get an accurate test result. Your friend sounds like she's fantasizing about it and is trying to gain attention by claiming she's pregnant. A friend of mine did that back in the day and she did it to try to keep her b/f by her side. When he made her take a test in front of him, she refused then changed her story and said it was really a kidney infection. (Those 2 conditions are not able to be mixed up.)
