Pregnant?

Hey lovelies! So my boyfriend and I have been having sex for a few weeks now. The majority of the time we're safe about it (condoms), but sometimes he likes to tease me. He's never cum inside me, but he's had to pullout because he was about to. This was Thursday. I started ovulating on Friday/Saturday. Any chance I could get pregnant? If so, any ideas as to when I could start feeling symptoms?
