If you have a normal 28 day cycle, you are most likely to become pregnant when you have unprotected intercourse approximately 2 weeks before you anticipate your period to start.
Ovulation could occur early or late and not hit exactly in the middle of the cycle.

So, yes, you can get pregnant before and after your period.
