I have been keeping track of my temp with natural cycles and also using the clear blue digital ovulation. Clear Blue showed a static smiley face on the Monday cycle day 21 and ovulation was confirmed on the Wednesday (cycle day 23) with temp increase on Friday (cycle day 26) but now my ovulation confirmed date has moved to the Thursday why has this date now moved after a week of it being confirmed at day 23? Would i get a peak on Monday and ovulate 3 days later? Also is ovulation on day 24 too late to conceive?
