MC back in November at 11 weeks. Thought this AF seemed the first really normal one so had a lot of hope this month. Started OPK CD5 and got blank circle. Flashing smiley all through CD6 - 11 this morning CD12, back to blank circle. Been doing IC too, sometimes twice per day and all negative. FF says I should ov CD14 or 15. Bbt not detected anything. Had lots of ovulation cramps past two days, actually quite painful. Don't think I've ever had them before, or perhaps I just notice everything now. What could be going on? Have I missed Ov? Is it yet to come? Anyone else had flashing then blank but still positive a few days later?
