After having unprotected sex on may 9, 10 got my period on 12 it was 5 days cycle after that having pregnancy symptoms is there any chance of pregnancy?

NO: As you described, if you had your normal 5 day menses after sex, than had no sex since, you would not be pregnant. Best wishes.

Maybe: You need to check a pregnancy test especially if you have not had a cycle since 5/12/13. Did you have sex before the 9th and 10th? We're your cycles regular before this? If so then the reason for no period could be pregnancy.
