When I first missed my period I felt a little sick and thought I was possibly pregnant but I took a ton of tests at the time even a blood test and they were all negative. I believe the last test I took was when my period was 8 days late and it was negative as well. I am now 19 days late on my period and have even taken medication to try to get it to start and it still hasnt started. Is it possible I am pregnant? Should I test again? In your experience how late were you before your positive test?
