In brief: Yes

Yes you can get pregnant a day before your period.
This is because you may have ovulated late in the cycle or not yet ovulated. The menstrual period is triggered when an ovulatory cycle is not fertilized. It is always diagnosed after the fact. Ovulation predictor kits help you figure out when you are ovulating. Overall the conception rate is about 25% per cycle. This 25% is distributed mostly toward the middle of the cycle. Best to be safe and use more reliable family planning methods.
