Pregnant?

Hi so I just lost my virginity exactly one week ago, I wasn't prepared to have sex with the guy It just kind of happened. He basically slid inside me and we started having sex for about 20-30 seconds before I even registered what was happening and I got nervous and told him to put a condom on. So he did and we continued for another couple minutes then we Just stopped all together and he didn't come and neither did I. When we had sex it was about 8-9 days after my period and I might have been ovulating. Do you think he had pre cum already and could that 30 seconds of him in me get me
Pregnant??
