Would you class 'the day you ovulated' as the day you get a positive opk? I know they only detect the LH surge but I just wondered if that's what you do. I had a very dark positive opk this lunchtime so I know I am due to actually ovulate in the next 12-36 hours or so.... We've been having sex every other day so far (last time being day before yesterday) so want to do it again today. It's hard because our other kids are here ;) If I don't manage it today, what do you reckon chances of getting preggers considering last time we dtd? Cheers ladies X
