Me & my wife have made unprotected sex. she take ipill after 24 hours. after 10 days she got her regular period. there are any chance of pregnency?

No: If a female has a normal period, this activity indicates that no implantation of a fertilized egg has taken place. Without implantation of a fertilized egg, pregnancy is not possible.

Pregnancy?: Not if she had an actual period.Potential side effects w emergency contraception include menstrual flow changes (spotting, bleeding, early or late period). So if there is any question as to whether that bleeding was a period, then a pregnancy test would clarify the situation.
