Hi just had to drop in and wish you luck!
I've got my fingers crossed for you!
With my last pregnancy the line was so faint I thought it was a negative it wasn't till I took the test again a few days later that it showed up still faint tho, hubby went and got the first test from the bathroom and there was a line but so faint it could hardly be seen!
Best of luck with your blood test!
