Probs Negative, but not sure....

I usually use blue dye tests and I did when I was pregnant for my first born. I have seen other posts where lines have been seen where I think there is only one. My husband and I want another baby, but we started trying in July. It might take a little while, but ny job only has unpaid maternity leave, so we only have a few months a certain time of year to try (I'm a teacher).
