Detailed Answer:
Hello Dear,

Thanks for writing to us. Followings are my comments:

1) Yes, there is quite chance of being pregnant if you involved in unprotected sex just 3 days before your ovulation day.

Sperms can live for 72 - 96 hrs inside vagina or female genital tract and ovum can live for 12- 24 hrs after ovulation.

2) You should undergo one home pregnancy test if you have missed your period. It will help to clear your doubt.

Hope, I have answered your query. Wish your good health and take care.
