I'm not convinced by these either, but then I am so used to the disappointment of months on end without positive opks (internet cheapies though) that I guess I am just not wanting to get my hopes up. I had 7 days of flashing smilies and then I got a solid smiley on the 8th day (cycle day 15) so the timings would add up, so fingers crossed. I will find out tomorrow though as I am getting my 21 day bloods test done due to being on Clomid, I have annovulatory cycles so these bloods will tell me whether I ovulated or not I assume x
