Both with this pregnancy and with my angel's pregnancy I got my first positives from my cheap ebay hpt's I got the sensitive ones, and even then the first positives I got were super pale lines, but definitely visible when I held them under the light. I kept a first response test as my back up test and did one straight after I got the positive on the cheap hpt and the first response one then showed a nice strong second line.

Oh, actually, I'll post the link to the picture of my first 3 hpt's I did with this bub. The bottom two were done within minutes of each other and shows how sensitive the first response was in comparison to the ebay one. The ebay ones are fantastic for serial POAS-ers like me, because I didn't feel guilty testing from day 8 of the TWW
