I am not sure how late you are in your cycle, but it took 3 before I got a possitive and the third on was when I was 2 wks late. If I were you I would also use your very first morning pee b4 u eat or drink anything. So I would wait if I were you to take the second test to save money of buying more tests.
Still don't see it. I would say your are not pregnant. When is AF due? You could always get a blood test done at the Dr's office.
I personally don't see the 2nd line. I'd take the last test the day after your period is due. For some women the positive doesn't show up early. Didn't you say you're due on the 24th in your other post? Best wishes to you in either case. :-)
