so I'm fairly new to charting and this month started using opk. I'm on day 9 if cycle and I'm pretty sure I ovulate this early as I've got pregnant before (since miscarried) on this day of my cycle. I did an opk test early today and line was faint, thought by this evening line would have got darker but it didn't show at all. Could I still get the LG surge tomorrow or has it passed already? Also on fertility friend they only have 4 fertile days, why would this be? Pic below of calendar.

This was early opk.

this was this evening.

any help is greatly appreciated. thank you.
