Do you think I'm pregnant?

I started my last period on June 10th and I have a normal period. According to the ovulation calculator I should have ovulated on Friday the 24th and fertile Tuesday the 21st-Sunday 26th. I had sex on the 21st unprotected and I'm not on any birth control. We use the pull out method. I also had unprotected sex on the 22nd and my guy ejaculated, waited a few minutes and then put it back in. What are the chances that I'm going to be pregnant?
