Hi girls. I started charting this cycle - and as you can see it is a pretty long one (my last one was 100 days!). The problem is, FF keeps moving my O day - first it was cd50, then CD52, and now its moved it forward another couple of days. This is most likely because I haven't been charting CM, largely because it doesn't reveal much....

So what do you think? Did I O on CD50, or sometime later??????
