The bleeding could be your regular period or an implantation bleed. To see whether you are pregnant you may need to do a urine pregnancy test. You should perform this test after 2 week after you've had unprotected sex and do the test in the morning. You can also do a blood test for pregnancy which can be done earlier and is more sensitive.
