Hello all. What a hectic 48 hours. I have learnt two new things in as many days: Firstly, that it is indeed possible to have an LH surge on the same day as ovulation (hopeful), and second, that I do NOT always ovulate on day 15!! How do I know this? Fertilityfriend told me this morning that I ovulated yesterday (day 14). Actually, this is not strictly true; I did a hopeful and changed the 'expert settings' on the Detector Manual Override so that my primary fertility sign was my OPK (as opposed to basal body temps). I did this because today - when I expected a dip in temperature and hence ovulation - I've had a tiny increase in temp from yesterday. This caused fertilityfriend to pinpoint ovulation at CD12, which is impossible as my OPK smiley face appeared on CD13 at 7pm. So, when I told fertilityfriend to use my OPK as my primary fertility indicator it duly pinpointed ovulation at yesterday. Thankfully, we DTD yesterday and the evening before so the timing of sex is great if I did ov yesterday. However, I'm still pretty shocked as I've never ovulated as early as day 14 in the entire eight months I've been ttc. There is one other conclusion to all this, of course, which is that this is an anovulatory month 
This morning I received a letter inviting me for my ultrasound scan next Friday (10th), which is all very exciting. By then I will be 10DPO - would a scan at that early stage be able to pick up a teeny-weeny embryo?? Stupid question, eh? Of course it wouldn't. It's just kind of exciting; the thought that, if we were pregnant this month, it might be picked up when I go for my ultrasound!
If I can figure out the technology I will post my chart on here like you did, hopeful, so you can see what you make of it. The vertical blue line is because I have requested my OPK as my primary fertility indicator.
Somewhere, fingers crossed that AF stays away! And thank you very much for that list...tons of over-40s having babies!

Goth, could your 25 day cycle have been anovulatory? Apparently we all have at least two a year

Hippychicks, not much chance of me being skin & bone with the amount of biscuits I'm packing away these days. But thanks for your concern
