Hello,
Home pregnancy tests differ in their sensitivity (i.e., the ability to detect the hormone of pregnancy when it is present). The most sensitive of these are First Response Early Result and Clearblue Easy Earliest Results. The earliest either of these might detect a pregnancy would be at the time of the missed menses (generally ~two weeks after conception). When a HPT administered at the time of the missed menses returns negative it is recommended to repeat the test in a one week.
Best regards,

Thank you for your answer! I will retest- I did use the First Response yesterday and it was negative- but I still have not gotten my period. I had slight cramping last night and thought it might be here- but still nothing (and as I said- my periods are usually very very painful right before it starts- very bad cramps, bloating, breasts sooooo sore and very irritable- but I don't feel any of that!) So I will retest- but the waiting is killing me! I just want to get on with life and deal with it- no matter what the outcome is! :)
