Is there a chance I can be pregnant?

I had unprotected sex on the 25th December. I have done a test on Thursday but came out negative. Is there any chance I can be pregnant? my period is late I usually get it on time or day earlier. I’m not trying to get my hopes up coz I don’t want to get disappointed 😞😞 but I hope I’ll be pregnant and pray 🙏 girls pray for me please 😊😊😊😊
