Worried about my line progression...

Lauren
I got my first vvvfl this past Tuesday night ... and it it now Thursday morning where I'm at. I'm worried that the lines on my tests are not progressing the way they should...
After a miscarriage in September, I feel extemely anxious about this pregnancy - and keep trying to gear myself emotionally for 'the worst.' 
Any insight or ladies who had similar experiences with a positive pregnancy that progressed normally, please comment.
