Try not to worry too much honey. I also failed the first test (they didn't tell me what my score was though) and then went on to get the all clear when I had the second test. My OB told me that roughly 75% of women who don't pass the first one are fine when they have the second one.

I do however remember how worked up I got waiting to do the second test and then waiting to get the results... I'm also a fainter when it comes to needles so was petrified as well, but I put on by brave face and got through it, which I know you will too x
