Thanks Alicia & Lis. Lis, I tested on CD36. My previous two cycles had been 33 days with ) on day 19 or 20, but on this particular cycle I'd ovulated earlier (according to temps and an u/s that my FS did), so I must have been a good 20 days post-O. I've never been an early tester - too scared of disappointments!

I think 14 days is pretty average for luteal phase - never heard of 17, but it's not something I've really looked into. Why don't you wait 2 more days, then test. Less risk of a false negative that way, too. Good luck!!!
