Last day of period (start 21/4 -9days-). had unprotected sex. he did not ejaculate and he make sure his dry before entering. risk of getting pregnant?

Yes to risk: Depending on when the first day of your period was will help determine when you ovulated. If you have a 28 day cycle then you would have ovulated about 14 days after your started. So it sounds close. You will need to wait and see if you miss your period and check a pregnancy test. Although some tests say they can test before your period, they are not always reliable.
