Delayed period

Shei

Hi, is it normal to have your period delayed after having sex during my 2nd day of my last period? It was unprotected i know there are chances of pregnancy if you are in a 28 day cycle since the ovulation day is within the days of the sperm can survive inside but I am on a 32-34day length cycle on my period so i know i dont ovulate at 14th. Should i be worry??
