The chances are low, Hari beta. For pregnancy, it is important for the male sperm to go into the vagina of the woman and fertilize her ovum. Which can only be done by sexual intercourse. And sometimes periods are late because of tension, stress or hormonal changes - so it’s perhaps fear and nervousness more than anything else. Just relax. If you want to be double sure - do a home test - after 10 days of this act... and then NEVER have sex without a condom.
