Hi Deanne,

I'm no good at interpreting charts so won't offer any advice on your chart BUT wanted to let you know that it is totally possible to O without getting a positive OPK. The month I suceeded I actually used two different OPK brands with the same sample of urine and one gave me a positive whilst the other came up with nothing. I go on my CM more than OPK's.
Good luck and I hope you get a BFP really soon!
