Iv been using clear blue advanced digital ovulation tests for 2 months. 1st month I ovulated same time as glow predicted this month the clear blue advanced ovulation tests said I ovulated really late I had 6 days of high peak flashing smiley face then I got my solid smiley face , But I got my periods this morning a weak and a half early but according to the ovulation test I’m still in the 48r ovulating window this is never happened before any one else had this ?
