AF was 2wks late so DH made me buy a 2 pack home tester (i was sure my period was just late) and with the brand we got, + means positive and -- means negative... good old me got a | ... what's that supposed to mean?! hehe.. so we tried again the next morning only to get the exact same result. so we went to the doc's who did the same thing and the result was a very strong + and the blood test reconfirmed it. those at-home testers can be funny sometimes!
