Thanks, but it's not really looking anything but normal to me -- I usually have a triphasic pattern. It's just enhanced as my first three temps post-Ov were lower than they usually are. I'm still impressed by the stability of the temps since I've been on Metformin, but I've been pessimistic about the outcome this month since before I even ovulated!
Feeling very emotional/depressed today, so I think it will just be downhill from here to AF. I won't be testing and thankfully I'll be busy travelling until Sunday. FX AF comes swiftly from that and I can avoid too much pre-menstrual depression/anxiety.
