confused about opks. the top one is from 8/28, bottom one is from this morning... I'm expecting to ovulate this weekend... I didn't miss it did?? none of them look positive!

Keep testing, almost there 

Were you testing twice a day?

I would say keep testing and probably really soon you'll get a positive. Yesterday I took two tests because the previous day I thought I was just about there that I'd get my positive and didn't want to miss it but actually the morning one I took was just slightly lighter than the one I took the previous day and the one I took yesterday afternoon. I think it's just because it was my fmu and some say not to use that. So if that's what you did maybe it just did the same as mine. And now this morning a took a test and it's positive. So I'd say give it another day or so. Good luck!
