Hi,
It's day 17 of my cycle and my fertile window was around the 21st. My cycle lengths are always different between 22 days and 28 days. I have done another ovulation test today, just to be sure and as usual I've got the vertical line in the C bit and a very faint vertical line in the T part BUT immediately as I did the rest a horizontal line was through the whole lot and looked like 2 crosses in the T and C bits. Half hour later it has disappeared... Has anyone had this? Does it mean anything :( my clear blue digital test is a big circle saying not fertile....
