Hi Viviene
Aaaaw, sorry

got you purpledragon and mothercabbage, but PMA for next cycle!!!
I know, it is just too too confusing working out when you ovulate!!! lol... Cerena, I had a similar thing last cycle... I had positive OPK's on CD's 6 & 7, a big temp dip on CD 7, and then rise from CD 8... A few days later FF put in solid blue crosshairs so it was clearly convinced as was I that I had O'd... But then, right towards the end of my cycle FF suddenly changed it's mind one day and decided I'd O'd on CD 11!!!! Now my OPK on CD 10 had been more-or-less positive... I couldn't decide whether it was pos or not... but then I had (sorry tmi) 1 big load of ewcm. I don't really get much in the way of cm to really be able to tell to much by that, and same as you I thought it was just that you can get a bit after... and I wrote off the opk as neg as I was convinced I'd already O'd... I recorded my opk as neg on FF and didn't note the ewcm as it had been dry rest of the day... but even with just my temps FF was sure enough to change my O date... so I figure it must be right!!!! I guess really the thing to do is use FF as a guide, but don't flat out believe it... I kinda missed BD-ing at the best times because I was so convinced that I'd already O'd...

Just had a look at your chart too Cerena, and FF doesn't seem totally sure when you O'd either as the crosshairs are dotted not solid...
