9 flashing smileys and then nothing

Hi I have just had 9 flashing smiley faces 8 days in a row (I tested twice one of the days) I am currently on day 23 and have just got a blank circle result this morning. I had all the signs of ovulation and a slight line on a cheap test on day 15 but kept testing for the peak that never came. I have BDing everyday since day 11 bar yesterday I am feeling very confused
