I am 24.
Go spend more money!
Seriously, get another test, and wait for first morning urine and test then, and wait the right amount of time before reading it - don't look hours later or you may see an evap. line.
I have had a lot of tenderness (not really cramping) all week too.
Have you tested yet?
Gosh, it all depends on how long that test sat.
You are all so sweet.
I took another HPT yesterday and it came back positive.
Thank you for all the warm wishes.
