No go today

I took a test this morning, but only one line came through (the test line).
I am 5 days early - so I'll probably take another test in 2 days to give it more time. I'm still pretty confident, but as time progresses, my doubts are starting to take over. I really hope this is the month of success...waiting is definitely the hardest part because so many emotions run through my head...its driving me crazy!
