Mooshie, I think I have to agree with Bridee. I was convinced that I had a + opk because my thoughts were stuck in "a line is a line right?!" and it wasn't as dark as the control. It wasn't till the following morning that I saw a real line and I had no doubt that it was the surge. It was darker than the control line within a minute.

I say go with what you feel. Good Luck - hope you catch the eggy!
