If i have have regular sex with my wife??does her ovulation day changes because of sex??

Pas de tout!: The only way the ovulation day can change because of sex is if your wife got pregnant during her previous cycle. In this case she wouldn't ovulate again until after the birth of your child. Regular sex with your wife is a good thing and I encourage it for many reasons.

No: Ovulation is based on a woman's hormonal cycle. Sex does not effect this cycle.
