Ovulating on day 6?!?!??

Lauren

Im 4 days away from af (im irregular) so hoping af doesn't show up as we baby danced 3/2 days before and on the day of ovulation, i used a cheep opk test and got a line that almost matched then used the clear blue ovulation digital tests and these came up with a smiley face so we did it. The day after i retested and there was no surge so according to my app and my findings. I ovulated on day 6. Is this normal?!?! Im 10dpo tomorrow and sooo hoping im pregnant.
